-API Reference
-=============
-
-Includes
---------
-
-To use the public APIs, include ``nghttp2/nghttp2.h``::
-
-    #include <nghttp2/nghttp2.h>
-
-The header files are also available online: :doc:`nghttp2.h` and
-:doc:`nghttp2ver.h`.
-
-Remarks
--------
-
-Do not call `nghttp2_session_send()`, `nghttp2_session_mem_send()`,
-`nghttp2_session_recv()` or `nghttp2_session_mem_recv()` from the
-nghttp2 callback functions directly or indirectly. It will lead to the
-crash.  You can submit requests or frames in the callbacks then call
-these functions outside the callbacks.
-
-Currently, `nghttp2_session_send()` and `nghttp2_session_mem_send()`
-do not send client connection preface
-(:macro:`NGHTTP2_CLIENT_CONNECTION_PREFACE`).  The applications are
-responsible to send it before sending any HTTP/2 frames using these
-functions if :type:`nghttp2_session` is configured as client.
-Similarly, `nghttp2_session_recv()` and `nghttp2_session_mem_recv()`
-do not consume client connection preface.  The applications are
-responsible to receive it before calling these functions if
-:type:`nghttp2_session` is configured as server.

+    protocol comes  first.  This  is used  in both  ALPN and
+    NPN.  The parameter must be  delimited by a single comma
+    only  and any  white spaces  are  treated as  a part  of
+    protocol string.
+
+    Default: ``h2,h2-16,h2-14,http/1.1``
+
+.. option:: --h1
+
+    Short        hand         for        :option:`--npn-list`\=http/1.1
+    :option:`--no-tls-proto`\=http/1.1,    which   effectively    force
+    http/1.1 for both http and https URI.
+
+.. option:: --header-table-size=<SIZE>
+
+    Specify decoder header table size.
+
+    Default: ``4K``
+
+.. option:: --encoder-header-table-size=<SIZE>
+
+    Specify encoder header table size.  The decoder (server)
+    specifies  the maximum  dynamic table  size it  accepts.
+    Then the negotiated dynamic table size is the minimum of
+    this option value and the value which server specified.
+
+    Default: ``4K``
 
 .. option:: -v, --verbose
 
-    
     Output debug information.
 
 .. option:: --version
 
-    
     Display version information and exit.
 
 .. option:: -h, --help
 
-    
     Display this help and exit.
 
+
+
+The <SIZE> argument is an integer and an optional unit (e.g., 10K is
+10 * 1024).  Units are K, M and G (powers of 1024).
+
+The <DURATION> argument is an integer and an optional unit (e.g., 1s
+is 1 second and 500ms is 500 milliseconds).  Units are h, m, s or ms
+(hours, minutes, seconds and milliseconds, respectively).  If a unit
+is omitted, a second is used as unit.

+    (non-successful HTTP status code).
+  errored
+    The number of requests failed, except for HTTP level failures.
+    This is the subset of the number reported in ``failed`` and most
+    likely the network level failures or stream was reset by
+    RST_STREAM.
+  timeout
+    The number of requests whose connection timed out before they were
+    completed.   This  is  the  subset   of  the  number  reported  in
+    ``errored``.
+
+status codes
+  The number of status code h2load received.
+
+traffic
+  total
+    The number of bytes received from the server "on the wire".  If
+    requests were made via TLS, this value is the number of decrypted
+    bytes.
+  headers
+    The  number  of response  header  bytes  from the  server  without

+    compression.  Let ``decompressed(headers)`` to the number of bytes
+    used for header fields after decompression.  The ``space savings``
+    is calculated  by (1 - ``headers``  / ``decompressed(headers)``) *
+    100.  For HTTP/1.1, this is usually  0.00%, since it does not have
+    header compression.  For HTTP/2, it shows some insightful numbers.
+  data
+    The number of response body bytes received from the server.
+
+time for request
+  min
+    The minimum time taken for request and response.
+  max
+    The maximum time taken for request and response.
+  mean
+    The mean time taken for request and response.
+  sd
+    The standard deviation of the time taken for request and response.
+  +/- sd
+    The fraction of the number of requests within standard deviation

+
+FLOW CONTROL
+------------
+
+h2load sets large flow control window by default, and effectively
+disables flow control to avoid under utilization of server
+performance.  To set smaller flow control window, use :option:`-w` and
+:option:`-W` options.  For example, use ``-w16 -W16`` to set default
+window size described in HTTP/2 protocol specification.

+
+In the above figure, ``id`` means stream ID, and ``w`` means weight.
+The stream 0 is non-existence stream, and forms the root of the tree.
+The stream 7 and 9 are not used for now.
+
+The URIs given in the command-line depend on stream 11 with the weight
+given in :option:`-p` option, which defaults to 16.
+
+If :option:`-a` option is used, nghttp parses the resource pointed by
+URI given in command-line as html, and extracts resource links from
+it.  When requesting those resources, nghttp uses dependency according
+to its resource type.
+
+For CSS, and Javascript files inside "head" element, they depend on
+stream 3 with the weight 2.  The Javascript files outside "head"
+element depend on stream 5 with the weight 2.  The mages depend on
+stream 11 with the weight 12.  The other resources (e.g., icon) depend
+on stream 11 with the weight 2.

+
+*/etc/nghttpx/nghttpx.conf*
+  The default configuration file path nghttpx searches at startup.
+  The configuration file path can be changed using :option:`--conf`
+  option.
+
+  Those lines which are staring ``#`` are treated as comment.
+
+  The option name in the configuration file is the long command-line
+  option name with leading ``--`` stripped (e.g., ``frontend``).  Put
+  ``=`` between option name and value.  Don't put extra leading or
+  trailing spaces.
+
+  When specifying arguments including characters which have special
+  meaning to a shell, we usually use quotes so that shell does not
+  interpret them.  When writing this configuration file, quotes for
+  this purpose must not be used.  For example, specify additional
+  request header field, do this:
+
+  .. code-block:: text
+
+    add-request-header=foo: bar
+
+  instead of:
+
+  .. code-block:: text
+
+    add-request-header="foo: bar"
+
+  The options which do not take argument in the command-line *take*
+  argument in the configuration file.  Specify ``yes`` as an argument
+  (e.g., ``http2-proxy=yes``).  If other string is given, it is
+  ignored.
+
+  To specify private key and certificate file which are given as
+  positional arguments in command-line, use ``private-key-file`` and
+  ``certificate-file``.
+
+  :option:`--conf` option cannot be used in the configuration file and
+  will be ignored if specified.
+
+Error log
+  Error log is written to stderr by default.  It can be configured
+  using :option:`--errorlog-file`.  The format of log message is as
+  follows:
+
+  <datetime> <master-pid> <current-pid> <thread-id> <level> (<filename>:<line>) <msg>
+
+  <datetime>
+    It is a combination of date and time when the log is written.  It
+    is in ISO 8601 format.
+
+  <master-pid>
+    It is a master process ID.
+
+  <current-pid>
+    It is a process ID which writes this log.
+
+  <thread-id>
+    It is a thread ID which writes this log.  It would be unique
+    within <current-pid>.
+
+  <filename> and <line>
+    They are source file name, and line number which produce this log.
+
+  <msg>
+    It is a log message body.
+
+SIGNALS
+-------
+
+SIGQUIT
+  Shutdown gracefully.  First accept pending connections and stop
+  accepting connection.  After all connections are handled, nghttpx
+  exits.
+
+SIGHUP
+  Reload configuration file given in :option:`--conf`.
+
+SIGUSR1
+  Reopen log files.
+
+SIGUSR2
+
+  Fork and execute nghttpx.  It will execute the binary in the same
+  path with same command-line arguments and environment variables.  As
+  of nghttpx version 1.20.0, the new master process sends SIGQUIT to
+  the original master process when it is ready to serve requests.  For
+  the earlier versions of nghttpx, user has to send SIGQUIT to the
+  original master process.
+
+  The difference between SIGUSR2 (+ SIGQUIT) and SIGHUP is that former
+  is usually used to execute new binary, and the master process is
+  newly spawned.  On the other hand, the latter just reloads
+  configuration file, and the same master process continues to exist.
+
+.. note::
+
+  nghttpx consists of multiple processes: one process for processing
+  these signals, and another one for processing requests.  The former
+  spawns the latter.  The former is called master process, and the
+  latter is called worker process.  If neverbleed is enabled, the
+  worker process spawns neverbleed daemon process which does RSA key
+  processing.  The above signal must be sent to the master process.
+  If the other processes received one of them, it is ignored.  This
+  behaviour of these processes may change in the future release.  In
+  other words, in the future release, the processes other than master
+  process may terminate upon the reception of these signals.
+  Therefore these signals should not be sent to the processes other
+  than master process.
+
+SERVER PUSH
+-----------
+
+nghttpx supports HTTP/2 server push in default mode with Link header
+field.  nghttpx looks for Link header field (`RFC 5988
+<http://tools.ietf.org/html/rfc5988>`_) in response headers from
+backend server and extracts URI-reference with parameter
+``rel=preload`` (see `preload
+<http://w3c.github.io/preload/#interoperability-with-http-link-header>`_)
+and pushes those URIs to the frontend client. Here is a sample Link
+header field to initiate server push:
+
+.. code-block:: text
+
+  Link: </fonts/font.woff>; rel=preload
+  Link: </css/theme.css>; rel=preload
+
+Currently, the following restriction is applied for server push:
+
+1. The associated stream must have method "GET" or "POST".  The
+   associated stream's status code must be 200.
+
+This limitation may be loosened in the future release.
+
+nghttpx also supports server push if both frontend and backend are
+HTTP/2 in default mode.  In this case, in addition to server push via
+Link header field, server push from backend is forwarded to frontend
+HTTP/2 session.
+
+HTTP/2 server push will be disabled if :option:`--http2-proxy` is
+used.
+
+UNIX DOMAIN SOCKET
+------------------
+
+nghttpx supports UNIX domain socket with a filename for both frontend
+and backend connections.
+
+Please note that current nghttpx implementation does not delete a
+socket with a filename.  And on start up, if nghttpx detects that the
+specified socket already exists in the file system, nghttpx first
+deletes it.  However, if SIGUSR2 is used to execute new binary and
+both old and new configurations use same filename, new binary does not
+delete the socket and continues to use it.
+
+OCSP STAPLING
+-------------
+
+OCSP query is done using external Python script
+``fetch-ocsp-response``, which has been originally developed in Perl
+as part of h2o project (https://github.com/h2o/h2o), and was
+translated into Python.
+
+The script file is usually installed under
+``$(prefix)/share/nghttp2/`` directory.  The actual path to script can
+be customized using :option:`--fetch-ocsp-response-file` option.
+
+If OCSP query is failed, previous OCSP response, if any, is continued
+to be used.
+
+:option:`--fetch-ocsp-response-file` option provides wide range of
+possibility to manage OCSP response.  It can take an arbitrary script
+or executable.  The requirement is that it supports the command-line
+interface of ``fetch-ocsp-response`` script, and it must return a
+valid DER encoded OCSP response on success.  It must return exit code
+0 on success, and 75 for temporary error, and the other error code for
+generic failure.  For large cluster of servers, it is not efficient
+for each server to perform OCSP query using ``fetch-ocsp-response``.
+Instead, you can retrieve OCSP response in some way, and store it in a
+disk or a shared database.  Then specify a program in
+:option:`--fetch-ocsp-response-file` to fetch it from those stores.
+This could provide a way to share the OCSP response between fleet of
+servers, and also any OCSP query strategy can be applied which may be
+beyond the ability of nghttpx itself or ``fetch-ocsp-response``
+script.
+
+TLS SESSION RESUMPTION
+----------------------
+
+nghttpx supports TLS session resumption through both session ID and
+session ticket.
+
+SESSION ID RESUMPTION
+~~~~~~~~~~~~~~~~~~~~~
+
+By default, session ID is shared by all worker threads.
+
+If :option:`--tls-session-cache-memcached` is given, nghttpx will
+insert serialized session data to memcached with
+``nghttpx:tls-session-cache:`` + lowercase hex string of session ID
+as a memcached entry key, with expiry time 12 hours.  Session timeout
+is set to 12 hours.
+
+By default, connections to memcached server are not encrypted.  To
+enable encryption, use ``tls`` keyword in
+:option:`--tls-session-cache-memcached` option.
+
+TLS SESSION TICKET RESUMPTION
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+By default, session ticket is shared by all worker threads.  The
+automatic key rotation is also enabled by default.  Every an hour, new
+encryption key is generated, and previous encryption key becomes
+decryption only key.  We set session timeout to 12 hours, and thus we
+keep at most 12 keys.
+
+If :option:`--tls-ticket-key-memcached` is given, encryption keys are
+retrieved from memcached.  nghttpx just reads keys from memcached; one
+has to deploy key generator program to update keys frequently (e.g.,
+every 1 hour).  The example key generator tlsticketupdate.go is
+available under contrib directory in nghttp2 archive.  The memcached
+entry key is ``nghttpx:tls-ticket-key``.  The data format stored in
+memcached is the binary format described below:
+
+.. code-block:: text
+
+    +--------------+-------+----------------+
+    | VERSION (4)  |LEN (2)|KEY(48 or 80) ...
+    +--------------+-------+----------------+
+                   ^                        |
+		   |                        |
+		   +------------------------+
+                   (LEN, KEY) pair can be repeated
+
+All numbers in the above figure is bytes.  All integer fields are
+network byte order.
+
+First 4 bytes integer VERSION field, which must be 1.  The 2 bytes
+integer LEN field gives the length of following KEY field, which
+contains key.  If :option:`--tls-ticket-key-cipher`\=aes-128-cbc is
+used, LEN must be 48.  If
+:option:`--tls-ticket-key-cipher`\=aes-256-cbc is used, LEN must be
+80.  LEN and KEY pair can be repeated multiple times to store multiple
+keys.  The key appeared first is used as encryption key.  All the
+remaining keys are used as decryption only.
+
+By default, connections to memcached server are not encrypted.  To
+enable encryption, use ``tls`` keyword in
+:option:`--tls-ticket-key-memcached` option.
+
+If :option:`--tls-ticket-key-file` is given, encryption key is read
+from the given file.  In this case, nghttpx does not rotate key
+automatically.  To rotate key, one has to restart nghttpx (see
+SIGNALS).
+
+CERTIFICATE TRANSPARENCY
+------------------------
+
+nghttpx supports TLS ``signed_certificate_timestamp`` extension (`RFC
+6962 <https://tools.ietf.org/html/rfc6962>`_).  The relevant options
+are :option:`--tls-sct-dir` and ``sct-dir`` parameter in
+:option:`--subcert`.  They takes a directory, and nghttpx reads all
+files whose extension is ``.sct`` under the directory.  The ``*.sct``
+files are encoded as ``SignedCertificateTimestamp`` struct described
+in `section 3.2 of RFC 69662
+<https://tools.ietf.org/html/rfc6962#section-3.2>`_.  This format is
+the same one used by `nginx-ct
+<https://github.com/grahamedgecombe/nginx-ct>`_ and `mod_ssl_ct
+<https://httpd.apache.org/docs/trunk/mod/mod_ssl_ct.html>`_.
+`ct-submit <https://github.com/grahamedgecombe/ct-submit>`_ can be
+used to submit certificates to log servers, and obtain the
+``SignedCertificateTimestamp`` struct which can be used with nghttpx.
+
+MRUBY SCRIPTING
+---------------
+
+.. warning::
+
+  The current mruby extension API is experimental and not frozen.  The
+  API is subject to change in the future release.
+
+.. warning::
+
+  Almost all string value returned from method, or attribute is a
+  fresh new mruby string, which involves memory allocation, and
+  copies.  Therefore, it is strongly recommended to store a return
+  value in a local variable, and use it, instead of calling method or
+  accessing attribute repeatedly.
+
+nghttpx allows users to extend its capability using mruby scripts.
+nghttpx has 2 hook points to execute mruby script: request phase and
+response phase.  The request phase hook is invoked after all request
+header fields are received from client.  The response phase hook is
+invoked after all response header fields are received from backend
+server.  These hooks allows users to modify header fields, or common
+HTTP variables, like authority or request path, and even return custom
+response without forwarding request to backend servers.
+
+To specify mruby script file, use :option:`--mruby-file` option.  The
+script will be evaluated once per thread on startup, and it must
+instantiate object and evaluate it as the return value (e.g.,
+``App.new``).  This object is called app object.  If app object
+defines ``on_req`` method, it is called with :rb:class:`Nghttpx::Env`
+object on request hook.  Similarly, if app object defines ``on_resp``
+method, it is called with :rb:class:`Nghttpx::Env` object on response
+hook.  For each method invocation, user can can access
+:rb:class:`Nghttpx::Request` and :rb:class:`Nghttpx::Response` objects
+via :rb:attr:`Nghttpx::Env#req` and :rb:attr:`Nghttpx::Env#resp`
+respectively.
+
+.. rb:module:: Nghttpx
+
+.. rb:const:: REQUEST_PHASE
+
+    Constant to represent request phase.
+
+.. rb:const:: RESPONSE_PHASE
+
+    Constant to represent response phase.
+
+.. rb:class:: Env
+
+    Object to represent current request specific context.
+
+    .. rb:attr_reader:: req
+
+        Return :rb:class:`Request` object.
+
+    .. rb:attr_reader:: resp
+
+        Return :rb:class:`Response` object.
+
+    .. rb:attr_reader:: ctx
+
+        Return Ruby hash object.  It persists until request finishes.
+        So values set in request phase hook can be retrieved in
+        response phase hook.
+
+    .. rb:attr_reader:: phase
+
+        Return the current phase.
+
+    .. rb:attr_reader:: remote_addr
+
+        Return IP address of a remote client.  If connection is made
+        via UNIX domain socket, this returns the string "localhost".
+
+    .. rb:attr_reader:: server_addr
+
+        Return address of server that accepted the connection.  This
+	is a string which specified in :option:`--frontend` option,
+	excluding port number, and not a resolved IP address.  For
+	UNIX domain socket, this is a path to UNIX domain socket.
+
+    .. rb:attr_reader:: server_port
+
+        Return port number of the server frontend which accepted the
+        connection from client.
+
+    .. rb:attr_reader:: tls_used
+
+        Return true if TLS is used on the connection.
+
+    .. rb:attr_reader:: tls_sni
+
+        Return the TLS SNI value which client sent in this connection.
+
+    .. rb:attr_reader:: tls_client_fingerprint_sha256
+
+        Return the SHA-256 fingerprint of a client certificate.
+
+    .. rb:attr_reader:: tls_client_fingerprint_sha1
+
+        Return the SHA-1 fingerprint of a client certificate.
+
+    .. rb:attr_reader:: tls_client_issuer_name
+
+        Return the issuer name of a client certificate.
+
+    .. rb:attr_reader:: tls_client_subject_name
+
+        Return the subject name of a client certificate.
+
+    .. rb:attr_reader:: tls_client_serial
+
+        Return the serial number of a client certificate.
+
+    .. rb:attr_reader:: tls_client_not_before
+
+        Return the start date of a client certificate in seconds since
+        the epoch.
+
+    .. rb:attr_reader:: tls_client_not_after
+
+        Return the end date of a client certificate in seconds since
+        the epoch.
+
+    .. rb:attr_reader:: tls_cipher
+
+        Return a TLS cipher negotiated in this connection.
+
+    .. rb:attr_reader:: tls_protocol
+
+        Return a TLS protocol version negotiated in this connection.
+
+    .. rb:attr_reader:: tls_session_id
+
+        Return a session ID for this connection in hex string.
+
+    .. rb:attr_reader:: tls_session_reused
+
+        Return true if, and only if a SSL/TLS session is reused.
+
+    .. rb:attr_reader:: alpn
+
+        Return ALPN identifier negotiated in this connection.
+
+.. rb:class:: Request
+
+    Object to represent request from client.  The modification to
+    Request object is allowed only in request phase hook.
+
+    .. rb:attr_reader:: http_version_major
+
+        Return HTTP major version.
+
+    .. rb:attr_reader:: http_version_minor
+
+        Return HTTP minor version.
+
+    .. rb:attr_accessor:: method
+
+        HTTP method.  On assignment, copy of given value is assigned.
+        We don't accept arbitrary method name.  We will document them
+        later, but well known methods, like GET, PUT and POST, are all
+        supported.
+
+    .. rb:attr_accessor:: authority
+
+        Authority (i.e., example.org), including optional port
+        component .  On assignment, copy of given value is assigned.
+
+    .. rb:attr_accessor:: scheme
+
+        Scheme (i.e., http, https).  On assignment, copy of given
+        value is assigned.
+
+    .. rb:attr_accessor:: path
+
+        Request path, including query component (i.e., /index.html).
+        On assignment, copy of given value is assigned.  The path does
+        not include authority component of URI.  This may include
+        query component.  nghttpx makes certain normalization for
+        path.  It decodes percent-encoding for unreserved characters
+        (see https://tools.ietf.org/html/rfc3986#section-2.3), and
+        resolves ".." and ".".  But it may leave characters which
+        should be percent-encoded as is. So be careful when comparing
+        path against desired string.
+
+    .. rb:attr_reader:: headers
+
+        Return Ruby hash containing copy of request header fields.
+        Changing values in returned hash does not change request
+        header fields actually used in request processing.  Use
+        :rb:meth:`Nghttpx::Request#add_header` or
+        :rb:meth:`Nghttpx::Request#set_header` to change request
+        header fields.
+
+    .. rb:method:: add_header(key, value)
+
+        Add header entry associated with key.  The value can be single
+        string or array of string.  It does not replace any existing
+        values associated with key.
+
+    .. rb:method:: set_header(key, value)
+
+        Set header entry associated with key.  The value can be single
+        string or array of string.  It replaces any existing values
+        associated with key.
+
+    .. rb:method:: clear_headers
+
+        Clear all existing request header fields.
+
+    .. rb:method:: push(uri)
+
+        Initiate to push resource identified by *uri*.  Only HTTP/2
+        protocol supports this feature.  For the other protocols, this
+        method is noop.  *uri* can be absolute URI, absolute path or
+        relative path to the current request.  For absolute or
+        relative path, scheme and authority are inherited from the
+        current request.  Currently, method is always GET.  nghttpx
+        will issue request to backend servers to fulfill this request.
+        The request and response phase hooks will be called for pushed
+        resource as well.
+
+.. rb:class:: Response
+
+    Object to represent response from backend server.
+
+    .. rb:attr_reader:: http_version_major
+
+        Return HTTP major version.
+
+    .. rb:attr_reader:: http_version_minor
+
+        Return HTTP minor version.
+
+    .. rb:attr_accessor:: status
+
+        HTTP status code.  It must be in the range [200, 999],
+        inclusive.  The non-final status code is not supported in
+        mruby scripting at the moment.
+
+    .. rb:attr_reader:: headers
+
+        Return Ruby hash containing copy of response header fields.
+        Changing values in returned hash does not change response
+        header fields actually used in response processing.  Use
+        :rb:meth:`Nghttpx::Response#add_header` or
+        :rb:meth:`Nghttpx::Response#set_header` to change response
+        header fields.
+
+    .. rb:method:: add_header(key, value)
+
+        Add header entry associated with key.  The value can be single
+        string or array of string.  It does not replace any existing
+        values associated with key.
+
+    .. rb:method:: set_header(key, value)
+
+        Set header entry associated with key.  The value can be single
+        string or array of string.  It replaces any existing values
+        associated with key.
+
+    .. rb:method:: clear_headers
+
+        Clear all existing response header fields.
+
+    .. rb:method:: return(body)
+
+        Return custom response *body* to a client.  When this method
+        is called in request phase hook, the request is not forwarded
+        to the backend, and response phase hook for this request will
+        not be invoked.  When this method is called in response phase
+        hook, response from backend server is canceled and discarded.
+        The status code and response header fields should be set
+        before using this method.  To set status code, use :rb:meth To
+        set response header fields, use
+        :rb:attr:`Nghttpx::Response#status`.  If status code is not
+        set, 200 is used.  :rb:meth:`Nghttpx::Response#add_header` and
+        :rb:meth:`Nghttpx::Response#set_header`.  When this method is
+        invoked in response phase hook, the response headers are
+        filled with the ones received from backend server.  To send
+        completely custom header fields, first call
+        :rb:meth:`Nghttpx::Response#clear_headers` to erase all
+        existing header fields, and then add required header fields.
+        It is an error to call this method twice for a given request.
+
+    .. rb:method:: send_info(status, headers)
+
+        Send non-final (informational) response to a client.  *status*
+        must be in the range [100, 199], inclusive.  *headers* is a
+        hash containing response header fields.  Its key must be a
+        string, and the associated value must be either string or
+        array of strings.  Since this is not a final response, even if
+        this method is invoked, request is still forwarded to a
+        backend unless :rb:meth:`Nghttpx::Response#return` is called.
+        This method can be called multiple times.  It cannot be called
+        after :rb:meth:`Nghttpx::Response#return` is called.
+
+MRUBY EXAMPLES
+~~~~~~~~~~~~~~
+
+Modify request path:
+
+.. code-block:: ruby
+
+    class App
+      def on_req(env)
+        env.req.path = "/apps#{env.req.path}"
+      end
+    end
+
+    App.new
+
+Don't forget to instantiate and evaluate object at the last line.
+
+Restrict permission of viewing a content to a specific client
+addresses:
+
+.. code-block:: ruby
+
+    class App
+      def on_req(env)
+        allowed_clients = ["127.0.0.1", "::1"]
+
+        if env.req.path.start_with?("/log/") &&
+           !allowed_clients.include?(env.remote_addr) then
+          env.resp.status = 404
+          env.resp.return "permission denied"
+        end
+      end
+    end
+
+    App.new
+
+API ENDPOINTS
+-------------
+
+nghttpx exposes API endpoints to manipulate it via HTTP based API.  By
+default, API endpoint is disabled.  To enable it, add a dedicated
+frontend for API using :option:`--frontend` option with "api"
+parameter.  All requests which come from this frontend address, will
+be treated as API request.
+
+The response is normally JSON dictionary, and at least includes the
+following keys:
+
+status
+  The status of the request processing.  The following values are
+  defined:
+
+  Success
+    The request was successful.
+
+  Failure
+    The request was failed.  No change has been made.
+
+code
+  HTTP status code
+
+Additionally, depending on the API endpoint, ``data`` key may be
+present, and its value contains the API endpoint specific data.
+
+We wrote "normally", since nghttpx may return ordinal HTML response in
+some cases where the error has occurred before reaching API endpoint
+(e.g., header field is too large).
+
+The following section describes available API endpoints.
+
+POST /api/v1beta1/backendconfig
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This API replaces the current backend server settings with the
+requested ones.  The request method should be POST, but PUT is also
+acceptable.  The request body must be nghttpx configuration file
+format.  For configuration file format, see `FILES`_ section.  The
+line separator inside the request body must be single LF (0x0A).
+Currently, only :option:`backend <--backend>` option is parsed, the
+others are simply ignored.  The semantics of this API is replace the
+current backend with the backend options in request body.  Describe
+the desired set of backend severs, and nghttpx makes it happen.  If
+there is no :option:`backend <--backend>` option is found in request
+body, the current set of backend is replaced with the :option:`backend
+<--backend>` option's default value, which is ``127.0.0.1,80``.
+
+The replacement is done instantly without breaking existing
+connections or requests.  It also avoids any process creation as is
+the case with hot swapping with signals.
+
+The one limitation is that only numeric IP address is allowed in
+:option:`backend <--backend>` in request body unless "dns" parameter
+is used while non numeric hostname is allowed in command-line or
+configuration file is read using :option:`--conf`.
+
+GET /api/v1beta1/configrevision
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This API returns configuration revision of the current nghttpx.  The
+configuration revision is opaque string, and it changes after each
+reloading by SIGHUP.  With this API, an external application knows
+that whether nghttpx has finished reloading its configuration by
+comparing the configuration revisions between before and after
+reloading.  It is recommended to disable persistent (keep-alive)
+connection for this purpose in order to avoid to send a request using
+the reused connection which may bound to an old process.
+
+This API returns response including ``data`` key.  Its value is JSON
+object, and it contains at least the following key:
+
+configRevision
+  The configuration revision of the current nghttpx

+Programmers' Guide
+==================
+
+Architecture
+------------
+
+The most notable point in nghttp2 library architecture is it does not
+perform any I/O.  nghttp2 only performs HTTP/2 protocol stuff based on
+input byte strings.  It will calls callback functions set by
+applications while processing input.  The output of nghttp2 is just
+byte string.  An application is responsible to send these output to
+the remote peer.  The callback functions may be called while producing
+output.
+
+Not doing I/O makes embedding nghttp2 library in the existing code
+base very easy.  Usually, the existing applications have its own I/O
+event loops.  It is very hard to use nghttp2 in that situation if
+nghttp2 does its own I/O.  It also makes light weight language wrapper
+for nghttp2 easy with the same reason.  The down side is that an
+application author has to write more code to write complete
+application using nghttp2.  This is especially true for simple "toy"
+application.  For the real applications, however, this is not the
+case.  This is because you probably want to support HTTP/1 which
+nghttp2 does not provide, and to do that, you will need to write your
+own HTTP/1 stack or use existing third-party library, and bind them
+together with nghttp2 and I/O event loop.  In this point, not
+performing I/O in nghttp2 has more point than doing it.
+
+The primary object that an application uses is :type:`nghttp2_session`
+object, which is opaque struct and its details are hidden in order to
+ensure the upgrading its internal architecture without breaking the
+backward compatibility.  An application can set callbacks to
+:type:`nghttp2_session` object through the dedicated object and
+functions, and it also interacts with it via many API function calls.
+
+An application can create as many :type:`nghttp2_session` object as it
+wants.  But single :type:`nghttp2_session` object must be used by a
+single thread at the same time.  This is not so hard to enforce since
+most event-based architecture applications use is single thread per
+core, and handling one connection I/O is done by single thread.
+
+To feed input to :type:`nghttp2_session` object, one can use
+`nghttp2_session_recv()` or `nghttp2_session_mem_recv()` functions.
+They behave similarly, and the difference is that
+`nghttp2_session_recv()` will use :type:`nghttp2_read_callback` to get
+input.  On the other hand, `nghttp2_session_mem_recv()` will take
+input as its parameter.  If in doubt, use `nghttp2_session_mem_recv()`
+since it is simpler, and could be faster since it avoids calling
+callback function.
+
+To get output from :type:`nghttp2_session` object, one can use
+`nghttp2_session_send()` or `nghttp2_session_mem_send()`.  The
+difference between them is that the former uses
+:type:`nghttp2_send_callback` to pass output to an application.  On
+the other hand, the latter returns the output to the caller.  If in
+doubt, use `nghttp2_session_mem_send()` since it is simpler.  But
+`nghttp2_session_send()` might be easier to use if the output buffer
+an application has is fixed sized.
+
+In general, an application should call `nghttp2_session_mem_send()`
+when it gets input from underlying connection.  Since there is great
+chance to get something pushed into transmission queue while the call
+of `nghttp2_session_mem_send()`, it is recommended to call
+`nghttp2_session_mem_recv()` after `nghttp2_session_mem_send()`.
+
+There is a question when we are safe to close HTTP/2 session without
+waiting for the closure of underlying connection.  We offer 2 API
+calls for this: `nghttp2_session_want_read()` and
+`nghttp2_session_want_write()`.  If they both return 0, application
+can destroy :type:`nghttp2_session`, and then close the underlying
+connection.  But make sure that the buffered output has been
+transmitted to the peer before closing the connection when
+`nghttp2_session_mem_send()` is used, since
+`nghttp2_session_want_write()` does not take into account the
+transmission of the buffered data outside of :type:`nghttp2_session`.
+
+Includes
+--------
+
+To use the public APIs, include ``nghttp2/nghttp2.h``::
+
+    #include <nghttp2/nghttp2.h>
+
+The header files are also available online: :doc:`nghttp2.h` and
+:doc:`nghttp2ver.h`.
+
+Remarks
+-------
+
+Do not call `nghttp2_session_send()`, `nghttp2_session_mem_send()`,
+`nghttp2_session_recv()` or `nghttp2_session_mem_recv()` from the
+nghttp2 callback functions directly or indirectly. It will lead to the
+crash.  You can submit requests or frames in the callbacks then call
+these functions outside the callbacks.
+
+`nghttp2_session_send()` and `nghttp2_session_mem_send()` send first
+24 bytes of client magic string (MAGIC)
+(:macro:`NGHTTP2_CLIENT_MAGIC`) on client configuration.  The
+applications are responsible to send SETTINGS frame as part of
+connection preface using `nghttp2_submit_settings()`.  Similarly,
+`nghttp2_session_recv()` and `nghttp2_session_mem_recv()` consume
+MAGIC on server configuration unless
+`nghttp2_option_set_no_recv_client_magic()` is used with nonzero
+option value.
+
+.. _http-messaging:
+
+HTTP Messaging
+--------------
+
+By default, nghttp2 library checks HTTP messaging rules described in
+`HTTP/2 specification, section 8
+<https://tools.ietf.org/html/draft-ietf-httpbis-http2-17#section-8>`_.
+Everything described in that section is not validated however.  We
+briefly describe what the library does in this area.  In the following
+description, without loss of generality we omit CONTINUATION frame
+since they must follow HEADERS frame and are processed atomically.  In
+other words, they are just one big HEADERS frame.  To disable these
+validations, use `nghttp2_option_set_no_http_messaging()`.  Please
+note that disabling this feature does not change the fundamental
+client and server model of HTTP.  That is, even if the validation is
+disabled, only client can send requests.
+
+For HTTP request, including those carried by PUSH_PROMISE, HTTP
+message starts with one HEADERS frame containing request headers.  It
+is followed by zero or more DATA frames containing request body, which
+is followed by zero or one HEADERS containing trailer headers.  The
+request headers must include ":scheme", ":method" and ":path" pseudo
+header fields unless ":method" is not "CONNECT".  ":authority" is
+optional, but nghttp2 requires either ":authority" or "Host" header
+field must be present.  If ":method" is "CONNECT", the request headers
+must include ":method" and ":authority" and must omit ":scheme" and
+":path".
+
+For HTTP response, HTTP message starts with zero or more HEADERS
+frames containing non-final response (status code 1xx).  They are
+followed by one HEADERS frame containing final response headers
+(non-1xx).  It is followed by zero or more DATA frames containing
+response body, which is followed by zero or one HEADERS containing
+trailer headers.  The non-final and final response headers must
+contain ":status" pseudo header field containing 3 digits only.
+
+All request and response headers must include exactly one valid value
+for each pseudo header field.  Additionally nghttp2 requires all
+request headers must not include more than one "Host" header field.
+
+HTTP/2 prohibits connection-specific header fields.  The following
+header fields must not appear: "Connection", "Keep-Alive",
+"Proxy-Connection", "Transfer-Encoding" and "Upgrade".  Additionally,
+"TE" header field must not include any value other than "trailers".
+
+Each header field name and value must obey the field-name and
+field-value production rules described in `RFC 7230, section
+3.2. <https://tools.ietf.org/html/rfc7230#section-3.2>`_.
+Additionally, all field name must be lower cased.  The invalid header
+fields are treated as stream error, and that stream is reset.  If
+application wants to treat these headers in their own way, use
+`nghttp2_on_invalid_header_callback
+<https://nghttp2.org/documentation/types.html#c.nghttp2_on_invalid_header_callback>`_.
+
+For "http" or "https" URIs, ":path" pseudo header fields must start
+with "/".  The only exception is OPTIONS request, in that case, "*" is
+allowed in ":path" pseudo header field to represent system-wide
+OPTIONS request.
+
+With the above validations, nghttp2 library guarantees that header
+field name passed to `nghttp2_on_header_callback()` is not empty.
+Also required pseudo headers are all present and not empty.
+
+nghttp2 enforces "Content-Length" validation as well.  All request or
+response headers must not contain more than one "Content-Length"
+header field.  If "Content-Length" header field is present, it must be
+parsed as 64 bit signed integer.  The sum of data length in the
+following DATA frames must match with the number in "Content-Length"
+header field if it is present (this does not include padding bytes).
+
+RFC 7230 says that server must not send "Content-Length" in any
+response with 1xx, and 204 status code.  It also says that
+"Content-Length" is not allowed in any response with 200 status code
+to a CONNECT request.  nghttp2 enforces them as well.
+
+Any deviation results in stream error of type PROTOCOL_ERROR.  If
+error is found in PUSH_PROMISE frame, stream error is raised against
+promised stream.
+
+The order of transmission of the HTTP/2 frames
+----------------------------------------------
+
+This section describes the internals of libnghttp2 about the
+scheduling of transmission of HTTP/2 frames.  This is pretty much
+internal stuff, so the details could change in the future versions of
+the library.
+
+libnghttp2 categorizes HTTP/2 frames into 4 categories: urgent,
+regular, syn_stream, and data in the order of higher priority.
+
+The urgent category includes PING and SETTINGS.  They are sent with
+highest priority.  The order inside the category is FIFO.
+
+The regular category includes frames other than PING, SETTINGS, DATA,
+and HEADERS which does not create stream (which counts toward
+concurrent stream limit).  The order inside the category is FIFO.
+
+The syn_stream category includes HEADERS frame which creates stream,
+that counts toward the concurrent stream limit.
+
+The data category includes DATA frame, and the scheduling among DATA
+frames are determined by HTTP/2 dependency tree.
+
+If the application wants to send frames in the specific order, and the
+default transmission order does not fit, it has to schedule frames by
+itself using the callbacks (e.g.,
+:type:`nghttp2_on_frame_send_callback`).
+
+RST_STREAM has special side effect when it is submitted by
+`nghttp2_submit_rst_stream()`.  It cancels all pending HEADERS and
+DATA frames whose stream ID matches the one in the RST_STREAM frame.
+This may cause unexpected behaviour for the application in some cases.
+For example, suppose that application wants to send RST_STREAM after
+sending response HEADERS and DATA.  Because of the reason we mentioned
+above, the following code does not work:
+
+.. code-block:: c
+
+    nghttp2_submit_response(...)
+    nghttp2_submit_rst_stream(...)
+
+RST_STREAM cancels HEADERS (and DATA), and just RST_STREAM is sent.
+The correct way is use :type:`nghttp2_on_frame_send_callback`, and
+after HEADERS and DATA frames are sent, issue
+`nghttp2_submit_rst_stream()`.  FYI,
+:type:`nghttp2_on_frame_not_send_callback` tells you why frames are
+not sent.
+
+Implement user defined HTTP/2 non-critical extensions
+-----------------------------------------------------
+
+As of nghttp2 v1.8.0, we have added HTTP/2 non-critical extension
+framework, which lets application send and receive user defined custom
+HTTP/2 non-critical extension frames.  nghttp2 also offers built-in
+functionality to send and receive official HTTP/2 extension frames
+(e.g., ALTSVC frame).  For these built-in handler, refer to the next
+section.
+
+To send extension frame, use `nghttp2_submit_extension()`, and
+implement :type:`nghttp2_pack_extension_callback`.  The callback
+implements how to encode data into wire format.  The callback must be
+set to :type:`nghttp2_session_callbacks` using
+`nghttp2_session_callbacks_set_pack_extension_callback()`.
+
+For example, we will illustrate how to send `ALTSVC
+<https://tools.ietf.org/html/draft-ietf-httpbis-alt-svc-14>`_ frame.
+
+.. code-block:: c
+
+    typedef struct {
+      const char *origin;
+      const char *field;
+    } alt_svc;
+
+    ssize_t pack_extension_callback(nghttp2_session *session, uint8_t *buf,
+                                    size_t len, const nghttp2_frame *frame,
+                                    void *user_data) {
+      const alt_svc *altsvc = (const alt_svc *)frame->ext.payload;
+      size_t originlen = strlen(altsvc->origin);
+      size_t fieldlen = strlen(altsvc->field);
+
+      uint8_t *p;
+
+      if (len < 2 + originlen + fieldlen || originlen > 0xffff) {
+        return NGHTTP2_ERR_CANCEL;
+      }
+
+      p = buf;
+      *p++ = originlen >> 8;
+      *p++ = originlen & 0xff;
+      memcpy(p, altsvc->origin, originlen);
+      p += originlen;
+      memcpy(p, altsvc->field, fieldlen);
+      p += fieldlen;
+
+      return p - buf;
+    }
+
+This implements :type:`nghttp2_pack_extension_callback`.  We have to
+set this callback to :type:`nghttp2_session_callbacks`:
+
+.. code-block:: c
+
+    nghttp2_session_callbacks_set_pack_extension_callback(
+        callbacks, pack_extension_callback);
+
+To send ALTSVC frame, call `nghttp2_submit_extension()`:
+
+.. code-block:: c
+
+  static const alt_svc altsvc = {"example.com", "h2=\":8000\""};
+
+  nghttp2_submit_extension(session, 0xa, NGHTTP2_FLAG_NONE, 0,
+                           (void *)&altsvc);
+
+Notice that ALTSVC is use frame type ``0xa``.
+
+To receive extension frames, implement 2 callbacks:
+:type:`nghttp2_unpack_extension_callback` and
+:type:`nghttp2_on_extension_chunk_recv_callback`.
+:type:`nghttp2_unpack_extension_callback` implements the way how to
+decode wire format.  :type:`nghttp2_on_extension_chunk_recv_callback`
+implements how to buffer the incoming extension payload.  These
+callbacks must be set using
+`nghttp2_session_callbacks_set_unpack_extension_callback()` and
+`nghttp2_session_callbacks_set_on_extension_chunk_recv_callback()`
+respectively.  The application also must tell the library which
+extension frame type it is willing to receive using
+`nghttp2_option_set_user_recv_extension_type()`.  Note that the
+application has to create :type:`nghttp2_option` object for that
+purpose, and initialize session with it.
+
+We use ALTSVC again to illustrate how to receive extension frames.  We
+use different ``alt_svc`` struct than the previous one.
+
+First implement 2 callbacks.  We store incoming ALTSVC payload to
+global variable ``altsvc_buffer``.  Don't do this in production code
+since this is not thread safe:
+
+.. code-block:: c
+
+    typedef struct {
+      const uint8_t *origin;
+      size_t originlen;
+      const uint8_t *field;
+      size_t fieldlen;
+    } alt_svc;
+
+    /* buffers incoming ALTSVC payload */
+    uint8_t altsvc_buffer[4096];
+    /* The length of byte written to altsvc_buffer */
+    size_t altsvc_bufferlen = 0;
+
+    int on_extension_chunk_recv_callback(nghttp2_session *session,
+                                         const nghttp2_frame_hd *hd,
+                                         const uint8_t *data, size_t len,
+                                         void *user_data) {
+      if (sizeof(altsvc_buffer) < altsvc_bufferlen + len) {
+        altsvc_bufferlen = 0;
+        return NGHTTP2_ERR_CANCEL;
+      }
+
+      memcpy(altsvc_buffer + altsvc_bufferlen, data, len);
+      altsvc_bufferlen += len;
+
+      return 0;
+    }
+
+    int unpack_extension_callback(nghttp2_session *session, void **payload,
+                                  const nghttp2_frame_hd *hd, void *user_data) {
+      uint8_t *origin, *field;
+      size_t originlen, fieldlen;
+      uint8_t *p, *end;
+      alt_svc *altsvc;
+
+      if (altsvc_bufferlen < 2) {
+        altsvc_bufferlen = 0;
+        return NGHTTP2_ERR_CANCEL;
+      }
+
+      p = altsvc_buffer;
+      end = altsvc_buffer + altsvc_bufferlen;
+
+      originlen = ((*p) << 8) + *(p + 1);
+      p += 2;
+
+      if (p + originlen > end) {
+        altsvc_bufferlen = 0;
+        return NGHTTP2_ERR_CANCEL;
+      }
+
+      origin = p;
+      field = p + originlen;
+      fieldlen = end - field;
+
+      altsvc = (alt_svc *)malloc(sizeof(alt_svc));
+      altsvc->origin = origin;
+      altsvc->originlen = originlen;
+      altsvc->field = field;
+      altsvc->fieldlen = fieldlen;
+
+      *payload = altsvc;
+
+      altsvc_bufferlen = 0;
+
+      return 0;
+    }
+
+Set these callbacks to :type:`nghttp2_session_callbacks`:
+
+.. code-block:: c
+
+    nghttp2_session_callbacks_set_on_extension_chunk_recv_callback(
+        callbacks, on_extension_chunk_recv_callback);
+
+    nghttp2_session_callbacks_set_unpack_extension_callback(
+        callbacks, unpack_extension_callback);
+
+
+In ``unpack_extension_callback`` above, we set unpacked ``alt_svc``
+object to ``*payload``.  nghttp2 library then, calls
+:type:`nghttp2_on_frame_recv_callback`, and ``*payload`` will be
+available as ``frame->ext.payload``:
+
+.. code-block:: c
+
+    int on_frame_recv_callback(nghttp2_session *session,
+                               const nghttp2_frame *frame, void *user_data) {
+
+      switch (frame->hd.type) {
+      ...
+      case 0xa: {
+        alt_svc *altsvc = (alt_svc *)frame->ext.payload;
+        fprintf(stderr, "ALTSVC frame received\n");
+        fprintf(stderr, " origin: %.*s\n", (int)altsvc->originlen, altsvc->origin);
+        fprintf(stderr, " field : %.*s\n", (int)altsvc->fieldlen, altsvc->field);
+        free(altsvc);
+        break;
+      }
+      }
+
+      return 0;
+    }
+
+Finally, application should set the extension frame types it is
+willing to receive:
+
+.. code-block:: c
+
+    nghttp2_option_set_user_recv_extension_type(option, 0xa);
+
+The :type:`nghttp2_option` must be set to :type:`nghttp2_session` on
+its creation:
+
+.. code-block:: c
+
+    nghttp2_session_client_new2(&session, callbacks, user_data, option);
+
+How to use built-in HTTP/2 extension frame handlers
+---------------------------------------------------
+
+In the previous section, we talked about the user defined HTTP/2
+extension frames.  In this section, we talk about HTTP/2 extension
+frame support built into nghttp2 library.
+
+As of this writing, nghttp2 supports ALTSVC extension frame.  To send
+ALTSVC frame, use `nghttp2_submit_altsvc()` function.
+
+To receive ALTSVC frame through built-in functionality, application
+has to use `nghttp2_option_set_builtin_recv_extension_type()` to
+indicate the willingness of receiving ALTSVC frame:
+
+.. code-block:: c
+
+    nghttp2_option_set_builtin_recv_extension_type(option, NGHTTP2_ALTSVC);
+
+This is very similar to the case when we used to receive user defined
+frames.
+
+If the same frame type is set using
+`nghttp2_option_set_builtin_recv_extension_type()` and
+`nghttp2_option_set_user_recv_extension_type()`, the latter takes
+precedence.  Application can implement its own frame handler rather
+than using built-in handler.
+
+The :type:`nghttp2_option` must be set to :type:`nghttp2_session` on
+its creation, like so:
+
+.. code-block:: c
+
+    nghttp2_session_client_new2(&session, callbacks, user_data, option);
+
+When ALTSVC is received, :type:`nghttp2_on_frame_recv_callback` will
+be called as usual.

 After prerequisite libraries are prepared, run ``android-config`` and
 then ``android-make`` to compile nghttp2 source files.
 
 If all went well, application binaries, such as nghttpx, are created

+Contribution Guidelines
+=======================
+
+[This text was composed based on 1.2. License section of curl/libcurl
+project.]
+
+When contributing with code, you agree to put your changes and new
+code under the same license nghttp2 is already using unless stated and
+agreed otherwise.
+
+When changing existing source code, you do not alter the copyright of
+the original file(s).  The copyright will still be owned by the
+original creator(s) or those who have been assigned copyright by the
+original author(s).
+
+By submitting a patch to the nghttp2 project, you are assumed to have
+the right to the code and to be allowed by your employer or whatever
+to hand over that patch/code to us.  We will credit you for your
+changes as far as possible, to give credit but also to keep a trace
+back to who made what changes.  Please always provide us with your
+full real name when contributing!
+
+Coding style
+------------
+
+We use clang-format to format source code consistently.  The
+clang-format configuration file .clang-format is located at the root
+directory.  Since clang-format produces slightly different results
+between versions, we currently use clang-format-5.0.
+
+To detect any violation to the coding style, we recommend to setup git
+pre-commit hook to check coding style of the changes you introduced.
+The pre-commit file is located at the root directory.  Copy it under
+.git/hooks and make sure that it is executable.  The pre-commit script
+uses clang-format-diff.py to detect any style errors.  If it is not in
+your PATH or it exists under different name (e.g.,
+clang-format-diff-5.0 in debian), either add it to PATH variable or
+add git option ``clangformatdiff.binary`` to point to the script.
+
+For emacs users, integrating clang-format to emacs is very easy.
+clang-format.el should come with clang distribution.  If it is not
+found, download it from `here
+<https://llvm.org/svn/llvm-project/cfe/trunk/tools/clang-format/clang-format.el>`_.
+And add these lines to your .emacs file:
+
+.. code-block:: lisp
+
+    ;; From
+    ;; https://code.google.com/p/chromium/wiki/Emacs#Use_Google's_C++_style!
+    (load "/<path/to>/clang-format.el")
+    (add-hook 'c-mode-common-hook
+         (function (lambda () (local-set-key (kbd "TAB")
+                                             'clang-format-region))))
