Update bash_completion

RFC 7540 does not enforce any limit on the number of incoming reserved
streams (in RFC 7540 terms, streams in reserved (remote) state).  This
only affects client side, since only server can push streams.
Malicious server can push arbitrary number of streams, and make
client's memory exhausted.  The new option,
nghttp2_set_max_reserved_remote_streams, can set the maximum number of
such incoming streams to avoid possible memory exhaustion.  If this
option is set, and pushed streams are automatically closed on
reception, without calling user provided callback, if they exceed the
given limit.  The default value is 200.  If session is configured as
server side, this option has no effect.  Server can control the number
of streams to push.

-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.

+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 and SPDY protocol specification.

+
+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 and SPDY protocol specification.

+.SH DEPENDENCY BASED PRIORITY
+.sp
+nghttp sends priority hints to server by default unless
+\fI\%\-\-no\-dep\fP is used.  nghttp mimics the way Firefox employs to
+manages dependency using idle streams.  We follows the behaviour of
+Firefox Nightly as of April, 2015, and nghttp\(aqs behaviour is very
+static and could be different from Firefox in detail.  But reproducing
+the same behaviour of Firefox is not our goal.  The goal is provide
+the easy way to test out the dependency priority in server
+implementation.
+.sp
+When connection is established, nghttp sends 5 PRIORITY frames to idle
+streams 3, 5, 7, 9 and 11 to create "anchor" nodes in dependency
+tree:

+In the above figure, \fBid\fP means stream ID, and \fBw\fP 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.
+.sp
+The URIs given in the command\-line depend on stream 11 with the weight
+given in \fI\%\-p\fP option, which defaults to 16.
+.sp
+If \fI\%\-a\fP 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.
+.sp
+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.

+
+DEPENDENCY BASED PRIORITY
+-------------------------
+
+nghttp sends priority hints to server by default unless
+:option:`--no-dep` is used.  nghttp mimics the way Firefox employs to
+manages dependency using idle streams.  We follows the behaviour of
+Firefox Nightly as of April, 2015, and nghttp's behaviour is very
+static and could be different from Firefox in detail.  But reproducing
+the same behaviour of Firefox is not our goal.  The goal is provide
+the easy way to test out the dependency priority in server
+implementation.
+
+When connection is established, nghttp sends 5 PRIORITY frames to idle
+streams 3, 5, 7, 9 and 11 to create "anchor" nodes in dependency
+tree::
+
+                      +-----+
+                      |id=0 |
+                      +-----+
+                     ^   ^   ^
+              w=201 /    |    \ w=1
+                   /     |     \
+                  / w=101|      \
+              +-----+ +-----+ +-----+
+              |id=3 | |id=5 | |id=7 |
+              +-----+ +-----+ +-----+

+              |id=11|         |id=9 |
+              +-----+         +-----+
+
+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.

+SIGNALS
+-------
+
+SIGQUIT
+  Shutdown gracefully.  First accept pending connections and stop
+  accepting connection.  After all connections are handled, nghttpx
+  exits.
+
+SIGUSR1
+  Reopen log files.

+  Fork and execute nghttpx.  It will execute the binary in the same

+  After new process comes up, sending SIGQUIT to the original process
+  to perform hot swapping.
+
+SERVER PUSH
+-----------
+
+nghttpx supports HTTP/2 server push in default mode.  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:: http
+
+  Link: </fonts/font.woff>; rel=preload
+  Link: </css/theme.css>; rel=preload
+
+Currently, the following restrictions are applied for server push:
+
+1. URI-reference must not contain authority.  If it exists, it is not
+   pushed.  ``/fonts/font.woff`` and ``css/theme.css`` are eligible to
+   be pushed.  ``https://example.org/fonts/font.woff`` and
+   ``//example.org/css/theme.css`` are not.
+
+2. The associated stream must have method "GET" or "POST".  The
+   associated stream's status code must be 200.
+
+These limitations may be loosened in the future release.
+
+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.
+
+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:`` + lowercased hex string of session ID
+as a memcached entry key, with expiry time 12 hours.  Session timeout
+is set to 12 hours.
+
+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::
+
+    +--------------+-------+----------------+
+    | 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.
+
+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).

+
+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()`.
+
+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.  While the pseudo
+header fields must satisfy these rules, we just ignore illegal regular
+headers (this means that these header fields are not passed to
+application callback).  This is because these illegal header fields
+are floating around in existing internet and resetting stream just
+because of this may break many web sites.  This is especially true if
+we forward to or translate from HTTP/1 traffic.
+
+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).
+
+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.

+
+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 which comes with
+clang-3.5.
+
+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-3.5 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:

+libnghttp2_asio: High level HTTP/2 C++ library
+==============================================
+
+libnghttp2_asio is C++ library built on top of libnghttp2 and provides
+high level abstraction API to build HTTP/2 applications.  It depends
+on Boost::ASIO library and OpenSSL.  Currently libnghttp2_asio
+provides server and client side API.
+
+libnghttp2_asio is not built by default.  Use ``--enable-asio-lib``
+configure flag to build libnghttp2_asio.  The required Boost libraries
+are:
+
+* Boost::Asio
+* Boost::System
+* Boost::Thread
+
+We have 3 header files for this library:
+
+* :doc:`asio_http2_server.h`
+* :doc:`asio_http2_client.h`
+* :doc:`asio_http2.h`
+
+asio_http2.h is included from the other two files.
+
+To build a program with libnghttp2_asio, link to the following
+libraries::
+
+    -lnghttp2_asio -lboost_system
+
+If ``boost::asio::ssl`` is used in application code, OpenSSL is also
+required in link line::
+
+    -lnghttp2_asio -lboost_system -lssl -lcrypto
+
+Server API
+----------
+
+To use server API, first include following header file:
+
+.. code-block:: cpp
+
+    #include <nghttp2/asio_http2_server.h>
+
+Also take a look at that header file :doc:`asio_http2_server.h`.
+
+Server API is designed to build HTTP/2 server very easily to utilize
+C++11 anonymous function and closure.  The bare minimum example of
+HTTP/2 server looks like this:
+
+.. code-block:: cpp
+
+    using namespace nghttp2::asio_http2;
+    using namespace nghttp2::asio_http2::server;
+
+    int main(int argc, char *argv[]) {
+      boost::system::error_code ec;
+      http2 server;
+
+      server.handle("/", [](const request &req, const response &res) {
+        res.write_head(200);
+        res.end("hello, world\n");
+      });
+
+      if (server.listen_and_serve(ec, "localhost", "3000")) {
+        std::cerr << "error: " << ec.message() << std::endl;
+      }
+    }
+
+First we instantiate ``nghttp2::asio_http2::server::http2`` object.
+``nghttp2::asio_http2::server::http2::handle`` function registers
+pattern and its handler function.  In this example, we register "/" as
+pattern, which matches all requests.  Then call
+``nghttp2::asio_http2::server::http2::listen_and_serve`` function with
+address and port to listen to.
+
+The ``req`` and ``res`` represent HTTP request and response
+respectively.  ``nghttp2::asio_http2_::server::response::write_head``
+constructs HTTP response header fields.  The first argument is HTTP
+status code, in the above example, which is 200.  The second argument,
+which is omitted in the above example, is additional header fields to
+send.
+
+``nghttp2::asio_http2::server::response::end`` sends response body.
+In the above example, we send string "hello, world".
+
+The life time of req and res object ends after the callback set by
+``nghttp2::asio_http2::server::response::on_close`` function.
+Application must not use those objects after this call.
+
+Serving static files and enabling SSL/TLS
++++++++++++++++++++++++++++++++++++++++++
+
+In this example, we serve a couple of static files and also enable
+SSL/TLS.
+
+.. code-block:: cpp
+
+    #include <nghttp2/asio_http2_server.h>
+
+    using namespace nghttp2::asio_http2;
+    using namespace nghttp2::asio_http2::server;
+
+    int main(int argc, char *argv[]) {
+      boost::system::error_code ec;
+      boost::asio::ssl::context tls(boost::asio::ssl::context::sslv23);
+
+      tls.use_private_key_file("server.key", boost::asio::ssl::context::pem);
+      tls.use_certificate_chain_file("server.crt");
+
+      configure_tls_context_easy(ec, tls);
+
+      http2 server;
+
+      server.handle("/index.html", [](const request &req, const response &res) {
+        res.write_head(200);
+        res.end(file_generator("index.html"));
+      });
+
+      if (server.listen_and_serve(ec, tls, "localhost", "3000")) {
+        std::cerr << "error: " << ec.message() << std::endl;
+      }
+    }
+
+We first create ``boost::asio::ssl::context`` object and set path to
+private key file and certificate file.
+``nghttp2::asio_http2::server::configure_tls_context_easy`` function
+configures SSL/TLS context object for HTTP/2 server use, including NPN
+callbacks.
+
+In the above example, if request path is "/index.html", we serve
+index.html file in the current working directory.
+``nghttp2::asio_http2::server::response::end`` has overload to take
+function of type ``nghttp2::asio_http2::generator_cb`` and application
+pass its implementation to generate response body.  For the
+convenience, libnghttp2_asio library provides
+``nghttp2::asio_http2::file_generator`` function to generate function
+to server static file.  If other resource is requested, server
+automatically responds with 404 status code.
+
+Server push
++++++++++++
+
+Server push is also supported.
+
+.. code-block:: cpp
+
+    #include <nghttp2/asio_http2_server.h>
+
+    using namespace nghttp2::asio_http2;
+    using namespace nghttp2::asio_http2::server;
+
+    int main(int argc, char *argv[]) {
+      boost::system::error_code ec;
+      boost::asio::ssl::context tls(boost::asio::ssl::context::sslv23);
+
+      tls.use_private_key_file("server.key", boost::asio::ssl::context::pem);
+      tls.use_certificate_chain_file("server.crt");
+
+      configure_tls_context_easy(ec, tls);
+
+      http2 server;
+
+      std::string style_css = "h1 { color: green; }";
+
+      server.handle("/", [&style_css](const request &req, const response &res) {
+        boost::system::error_code ec;
+        auto push = res.push(ec, "GET", "/style.css");
+        push->write_head(200);
+        push->end(style_css);
+
+        res.write_head(200);
+        res.end(R"(
+    <!DOCTYPE html><html lang="en">
+    <title>HTTP/2 FTW</title><body>
+    <link href="/style.css" rel="stylesheet" type="text/css">
+    <h1>This should be green</h1>
+    </body></html>
+    )");
+      });
+
+      server.handle("/style.css",
+                    [&style_css](const request &req, const response &res) {
+        res.write_head(200);
+        res.end(style_css);
+      });
+
+      if (server.listen_and_serve(ec, tls, "localhost", "3000")) {
+        std::cerr << "error: " << ec.message() << std::endl;
+      }
+    }
+
+When client requested any resource other than "/style.css", we push
+"/style.css".  To push resource, call
+``nghttp2::asio_http2::server::response::push`` function with desired
+method and path.  It returns another response object and use its
+functions to send push response.
+
+Enable multi-threading
+++++++++++++++++++++++
+
+Enabling multi-threading is very easy.  Just call
+``nghttp2::asio_http2::server::http2::num_threads`` function with the
+desired number of threads:
+
+.. code-block:: cpp
+
+    http2 server;
+
+    // Use 4 native threads
+    server.num_threads(4);
+
+Client API
+----------
+
+To use client API, first include following header file:
+
+.. code-block:: cpp
+
+    #include <nghttp2/asio_http2_client.h>
+
+Also take a look at that header file :doc:`asio_http2_client.h`.
+
+Here is the sample client code to access HTTP/2 server and print out
+response header fields and response body to the console screen:
+
+.. code-block:: cpp
+
+    #include <iostream>
+
+    #include <nghttp2/asio_http2_client.h>
+
+    using boost::asio::ip::tcp;
+
+    using namespace nghttp2::asio_http2;
+    using namespace nghttp2::asio_http2::client;
+
+    int main(int argc, char *argv[]) {
+      boost::system::error_code ec;
+      boost::asio::io_service io_service;
+
+      // connect to localhost:3000
+      session sess(io_service, "localhost", "3000");
+
+      sess.on_connect([&sess](tcp::resolver::iterator endpoint_it) {
+	boost::system::error_code ec;
+
+	auto req = sess.submit(ec, "GET", "http://localhost:3000/");
+
+	req->on_response([](const response &res) {
+	  // print status code and response header fields.
+	  std::cerr << "HTTP/2 " << res.status_code() << std::endl;
+	  for (auto &kv : res.header()) {
+	    std::cerr << kv.first << ": " << kv.second.value << "\n";
+	  }
+	  std::cerr << std::endl;
+
+	  res.on_data([](const uint8_t *data, std::size_t len) {
+	    std::cerr.write(reinterpret_cast<const char *>(data), len);
+	    std::cerr << std::endl;
+	  });
+	});
+
+	req->on_close([&sess](uint32_t error_code) {
+	  // shutdown session after first request was done.
+	  sess.shutdown();
+	});
+      });
+
+      sess.on_error([](const boost::system::error_code &ec) {
+	std::cerr << "error: " << ec.message() << std::endl;
+      });
+
+      io_service.run();
+    }
+
+``nghttp2::asio_http2::client::session`` object takes
+``boost::asio::io_service`` object and remote server address.  When
+connection is made, the callback function passed to
+``nghttp2::asio_http2::client::on_connect`` is invoked with connected
+address as its parameter.  After this callback call, use
+``nghttp2::asio_http2::session::submit`` to send request to the
+server.  You can submit multiple requests at once without waiting for
+the completion of previous request.
+
+The life time of req and res object ends after the callback set by
+``nghttp2::asio_http2::server::request::on_close`` function.
+Application must not use those objects after this call.
+
+Normally, client does not stop even after all requests are done unless
+connection is lost.  To stop client, call
+``nghttp2::asio_http2::server::session::shutdown()``.
+
+Recieve server push and enable SSL/TLS

+
+	auto req = sess.submit(ec, "GET", "http://localhost:3000/");
+
+	req->on_response([&sess](const response &res) {
+	  std::cerr << "response received!" << std::endl;
+	  res.on_data([&sess](const uint8_t *data, std::size_t len) {
+	    std::cerr.write(reinterpret_cast<const char *>(data), len);
+	    std::cerr << std::endl;
+	  });
+	});
+
+	req->on_push([](const request &push) {
+	  std::cerr << "push request received!" << std::endl;
+	  push.on_response([](const response &res) {
+	    std::cerr << "push response received!" << std::endl;
+	    res.on_data([](const uint8_t *data, std::size_t len) {
+	      std::cerr.write(reinterpret_cast<const char *>(data), len);

+
+      sess.on_error([](const boost::system::error_code &ec) {
+	std::cerr << "error: " << ec.message() << std::endl;
+      });
+
+      io_service.run();
+    }
+
+The above sample code demonstrates how to enable SSL/TLS and receive
+server push.  Currently,
+``nghttp2::asio_http2::client::configure_tls_context`` function setups
+NPN callbacks for SSL/TLS context for HTTP/2 use.
+
+To receive server push, use
+``nghttp2::asio_http2::client::request::on_push`` function to set
+callback function which is invoked when server push request is
+arrived.  The callback function takes
+``nghttp2::asio_http2::client::request`` object, which contains the
+pushed request.  To get server push response, set callback using
+``nghttp2::asio_http2::client::request::on_response``.
+
+As stated in the previous section, client does not stop automatically
+as long as HTTP/2 session is fine and connection is alive.  We don't
+call ``nghttp2::asio_http2::client::session::shutdown`` in this
+example, so the program does not terminate after all responses are
+received.  Hit Ctrl-C to terminate the program.
+
+Multiple concurrent requests

+	std::cerr << "error: " << ec.message() << std::endl;
+      });
+
+      io_service.run();
+    }
+
+Here is the sample to send 3 requests at once.  Depending on the
+server settings, these requests are processed out-of-order.  In this
+example, we have a trick to shutdown session after all requests were
+done.  We made ``count`` object which is shared pointer to int and is
+initialized to 3.  On each request closure (the invocation of the
+callback set by ``nghttp2::asio_http2::client::request::on_close``),
+we decrement the count.  If count becomes 0, we are sure that all
+requests have been done and initiate shutdown.

 ``--errorlog-file`` options.
+
+Multiple backend addresses
+--------------------------
+
+nghttpx supports multiple backend addresses.  To specify them, just
+use ``-b`` option repeatedly.  For example, to use backend1:8080 and
+backend2:8080, use command-line like this: ``-bbackend1,8080
+-bbackend2,8080``.  For HTTP/2 backend, see also
+``--backend-http2-connections-per-worker`` option.

 Deflating (encoding) headers
 ----------------------------
 
-First we need to initialize :type:`nghttp2_hd_deflater` object using
-`nghttp2_hd_deflate_new()` function::
+First we need to initialize a :type:`nghttp2_hd_deflater` object using
+the `nghttp2_hd_deflate_new()` function::
 
     int nghttp2_hd_deflate_new(nghttp2_hd_deflater **deflater_ptr,
                                size_t deflate_hd_table_bufsize_max);
 
-This function allocates :type:`nghttp2_hd_deflater` object and
-initializes it and assigns its pointer to ``*deflater_ptr`` passed by
-parameter.  The *deflate_hd_table_bufsize_max* is the upper bound of
-header table size the deflater will use.  This will limit the memory
-usage in deflater object for dynamic header table.  If you doubt, just

+the deflater will use.  This will limit the memory usage by the
+deflater object for the dynamic header table.  If in doubt, just
 specify 4096 here, which is the default upper bound of dynamic header
 table buffer size.
 
-To encode header fields, `nghttp2_hd_deflate_hd()` function::
+To encode header fields, use the `nghttp2_hd_deflate_hd()` function::
 
     ssize_t nghttp2_hd_deflate_hd(nghttp2_hd_deflater *deflater,
                                   uint8_t *buf, size_t buflen,
                                   const nghttp2_nv *nva, size_t nvlen);
 
 The *deflater* is the deflater object initialized by
-`nghttp2_hd_deflate_new()` function described above.  The *buf* is a
-pointer to buffer to store encoded byte string.  The *buflen* is
-capacity of *buf*.  The *nva* is a pointer to :type:`nghttp2_nv`,
-which is an array of header fields to deflate.  The *nvlen* is the
-number of header fields which *nva* contains.
+`nghttp2_hd_deflate_new()` described above. The encoded byte string is
+written to the buffer *buf*, which has length *buflen*.  The *nva* is
+a pointer to an array of headers fields, each of type
+:type:`nghttp2_nv`.  *nvlen* is the number of header fields which
+*nva* contains.
 
 It is important to initialize and assign all members of
-:type:`nghttp2_nv`.  If a header field should not be inserted in
-dynamic header table for a security reason, set
-:macro:`NGHTTP2_NV_FLAG_NO_INDEX` flag in :member:`nghttp2_nv.flags`.
+:type:`nghttp2_nv`. For security sensitive header fields (such as
+cookies), set the :macro:`NGHTTP2_NV_FLAG_NO_INDEX` flag in
+:member:`nghttp2_nv.flags`.  Setting this flag prevents recovery of
+sensitive header fields by compression based attacks: This is achieved
+by not inserting the header field into the dynamic header table.
 
 `nghttp2_hd_deflate_hd()` processes all headers given in *nva*.  The
 *nva* must include all request or response header fields to be sent in
 one HEADERS (or optionally following (multiple) CONTINUATION
 frame(s)).  The *buf* must have enough space to store the encoded
-result.  Otherwise, the function will fail.  To estimate the upper
-bound of encoded result, use `nghttp2_hd_deflate_bound()` function::
+result, otherwise the function will fail.  To estimate the upper bound
+of the encoded result length, use `nghttp2_hd_deflate_bound()`::
 
     size_t nghttp2_hd_deflate_bound(nghttp2_hd_deflater *deflater,
                                     const nghttp2_nv *nva, size_t nvlen);
 
-Pass this function with the same paramters *deflater*, *nva* and
-*nvlen* which will be passed to `nghttp2_hd_deflate_hd()`.
+Pass this function the same parameters (*deflater*, *nva*, and
+*nvlen*) which will be passed to `nghttp2_hd_deflate_hd()`.
 
-The subsequent call of `nghttp2_hd_deflate_hd()` will use current
-encoder state and perform differential encoding which is the
-fundamental compression gain for HPACK.
+Subsequent calls to `nghttp2_hd_deflate_hd()` will use the current
+encoder state and perform differential encoding, which yields HPAC's
+fundamental compression gain.
 
-Once `nghttp2_hd_deflate_hd()` fails, it cannot be undone and its
-further call with the same deflater object shall fail.  So it is very
-important to use `nghttp2_hd_deflate_bound()` to know the required
-size of buffer.
+If `nghttp2_hd_deflate_hd()` fails, the failure is fatal and any
+further calls with the same deflater object will fail.  Thus it's very
+important to use `nghttp2_hd_deflate_bound()` to determine the
+required size of the output buffer.
 
-To delete :type:`nghttp2_hd_deflater` object, use `nghttp2_hd_deflate_del()`
-function.
-
-.. note::
-
-   Generally, the order of header fields passed to
-   `nghttp2_hd_deflate_hd()` function is not preserved.  It is known
-   that the relative ordering of header fields which do not share the
-   same name is insignificant.  But some header fields sharing the
-   same name require the explicit ordering.  To preserve this
-   ordering, those header values are concatenated into single header
-   field value using NULL (0x00) as delimiter.  This is transparent to
-   HPACK API.  Therefore, the application should examine the inflated
-   header values and split into multiple header field values by NULL.
+To delete a :type:`nghttp2_hd_deflater` object, use the
+`nghttp2_hd_deflate_del()` function.
 
 Inflating (decoding) headers
 ----------------------------
 
-We use :type:`nghttp2_hd_inflater` object to inflate compressed header
-data.  To initialize the object, use `nghttp2_hd_inflate_new()`::
+A :type:`nghttp2_hd_inflater` object is used to inflate compressed
+header data.  To initialize the object, use
+`nghttp2_hd_inflate_new()`::
 
     int nghttp2_hd_inflate_new(nghttp2_hd_inflater **inflater_ptr);
 
-To inflate header data, use `nghttp2_hd_inflate_hd()` function::
+To inflate header data, use `nghttp2_hd_inflate_hd()`::
 
     ssize_t nghttp2_hd_inflate_hd(nghttp2_hd_inflater *inflater,
                                   nghttp2_nv *nv_out, int *inflate_flags,
                                   uint8_t *in, size_t inlen, int in_final);
 
+`nghttp2_hd_inflate_hd()` reads a stream of bytes and outputs a single
+header field at a time. Multiple calls are normally required to read a
+full stream of bytes and output all of the header fields.
+
 The *inflater* is the inflater object initialized above.  The *nv_out*
-is a pointer to :type:`nghttp2_nv` to store the result.  The *in* is a
-pointer to input data and *inlen* is its length.  The caller is not
-required to specify whole deflated header data to *in* at once.  It
-can call this function multiple times for portion of the data in
-streaming way.  If *in_final* is nonzero, it tells the function that
-the passed data is the final sequence of deflated header data.  The
-*inflate_flags* is output parameter and successful call of this
-function stores a set of flags in it.  It will be described later.

+be stored.  The *in* is a pointer to input data, and *inlen* is its

+*in_final* is nonzero, it tells the function that the passed data is
+the final sequence of deflated header data.
+
+The *inflate_flags* is an output parameter; on success the function
+sets it to a bitset of flags.  It will be described later.
 
 This function returns when each header field is inflated.  When this
-happens, the function sets :macro:`NGHTTP2_HD_INFLATE_EMIT` flag to
-*inflate_flag* parameter and header field is stored in *nv_out*.  The
-return value indicates the number of data read from *in* to processed
-so far.  It may be less than *inlen*.  The caller should call the
-function repeatedly until all data are processed by adjusting *in* and
-*inlen* with the processed bytes.

+appropriately.

 header fields even if *inlen* is 0 when *in_final* is nonzero, due to
