 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.

 ==================
 
-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`.

-
-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);

-    }
-
-    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.

-using :option:`--subcert` option.  It can be used multiple times.
+
+Client proxy mode
+-----------------
+
+If nghttpx is invoked with ``-p`` option, it operates in client proxy
+mode.  This mode behaves like `client mode`_, but it works like
+forward proxy.  So HTTP/1 request must include absolute URI in request
+line.
+
+HTTP/1 frontend connection can be upgraded to HTTP/2 using HTTP
+Upgrade.  To disable SSL/TLS in backend connection, use
+``--backend-no-tls`` option.
+
+By default, the number of backend HTTP/2 connections per worker
+(thread) is determined by number of ``-b`` option.  To adjust this
+value, use ``--backend-http2-connections-per-worker`` option.
+
+The backend server must be a HTTP/2 proxy.  You can use nghttpx in
+`HTTP/2 proxy mode`_ as backend server.  The one use-case of this mode
+is utilize existing HTTP/1 clients to test HTTP/2 connections between
+2 proxies. The another use-case is use this mode to aggregate local
+HTTP/1 connections to one HTTP/2 backend encrypted connection.  This
+makes HTTP/1 clients which does not support secure proxy can use
+secure HTTP/2 proxy via nghttpx client mode.
+
+Suppose that HTTP/2 proxy listens to port 8443, just like we saw in
+`HTTP/2 proxy mode`_.  To run nghttpx in client proxy mode to access
+that server, invoke nghttpx like this::
+
+    $ nghttpx -p -f127.0.0.1,8080 -b127.0.0.1,8443
+
+.. note::
+
+    You may need ``-k`` option if HTTP/2 server's certificate is
+    self-signed. But please note that it is insecure.
+
+Then you can use curl to issue HTTP request via HTTP/2 proxy::
+
+    $ curl --http-proxy=http://localhost:8080 http://www.google.com/
+
+You can configure web browser to use localhost:8080 as forward
+proxy.
+
+HTTP/2 bridge mode
+------------------
+
+If nghttpx is invoked with ``--http2-bridge`` option, it operates in
+HTTP/2 bridge mode.  The supported protocols in frontend connections
+are the same in `default mode`_.  The protocol in backend is HTTP/2
+only.
+
+With ``--frontend-no-tls`` option, SSL/TLS is turned off in frontend
+connection, so the connection gets insecure.  To disable SSL/TLS in
+backend connection, use ``--backend-no-tls`` option.
+
+By default, the number of backend HTTP/2 connections per worker
+(thread) is determined by number of ``-b`` option.  To adjust this
+value, use ``--backend-http2-connections-per-worker`` option.
+
+The backend server is supporsed to be a HTTP/2 web server or HTTP/2
+proxy.  If backend server is HTTP/2 proxy, use
+``--no-location-rewrite`` and ``--no-host-rewrite`` options to disable
+rewriting location, host and :authority header field.
+
+The use-case of this mode is aggregate the incoming connections to one
+HTTP/2 connection.  One backend HTTP/2 connection is created per
+worker (thread).
+
+Disable SSL/TLS
+---------------
+
+In `default mode`_, `HTTP/2 proxy mode`_ and `HTTP/2 bridge mode`_,
+frontend connections are encrypted with SSL/TLS by default.  To turn
+off SSL/TLS, use ``--frontend-no-tls`` option.  If this option is
+used, the private key and certificate are not required to run nghttpx.
+
+In `client mode`_, `client proxy mode`_ and `HTTP/2 bridge mode`_,

-host and path.  For example, to route request destined to host
-``doc.example.com`` to backend server ``docserv:3000``, you can write
-like so:
-
-.. code-block:: text
-
-   backend=docserv,3000;doc.example.com/
-
-When you write this option in command-line, you should enclose
-argument with single or double quotes, since the character ``;`` has a
-special meaning in shell.
-
-To route, request to request path whose prefix is ``/foo`` to backend
-server ``[::1]:8080``, you can write like so:
-
-.. code-block:: text
-
-   backend=::1,8080;/foo
-
-Of course, you can specify both host and request path at the same
-time:
-
-.. code-block:: text
-
-   backend=192.168.0.10,8080;example.com/foo
-
-We can use ``*`` in the left most position of host to achieve wildcard
-suffix match.  If ``*`` is the left most character, then the remaining
-string should match the request host suffix.  ``*`` must match at
-least one character.  For example, ``*.example.com`` matches
-``www.example.com`` and ``dev.example.com``, and does not match
-``example.com`` and ``nghttp2.org``.  The exact match (without ``*``)
-always takes precedence over wildcard match.
-
-One important thing you have to remember is that we have to specify
-default routing pattern for so called "catch all" pattern.  To write
-"catch all" pattern, just specify backend server address, without
-pattern.
-
-Usually, host is the value of ``Host`` header field.  In HTTP/2, the
-value of ``:authority`` pseudo header field is used.
-
-When you write multiple backend addresses sharing the same routing
-pattern, they are used as load balancing.  For example, to use 2
-servers ``serv1:3000`` and ``serv2:3000`` for request host
-``example.com`` and path ``/myservice``, you can write like so:
-
-.. code-block:: text
-
-   backend=serv1,3000;example.com/myservice
-   backend=serv2,3000;example.com/myservice
-
-You can also specify backend application protocol in
-:option:`--backend` option using ``proto`` keyword after pattern.
-Utilizing this allows ngttpx to route certain request to HTTP/2, other
-requests to HTTP/1.  For example, to route requests to ``/ws/`` in
-backend HTTP/1.1 connection, and use backend HTTP/2 for other
-requests, do this:
-
-.. code-block:: text
-
-   backend=serv1,3000;/;proto=h2
-   backend=serv1,3000;/ws/;proto=http/1.1
-
-The default backend protocol is HTTP/1.1.
-
-TLS can be enabled per pattern basis:
-
-.. code-block:: text
-
-   backend=serv1,8443;/;proto=h2;tls
-   backend=serv2,8080;/ws/;proto=http/1.1
-
-In the above case, connection to serv1 will be encrypted by TLS.  On
-the other hand, connection to serv2 will not be encrypted by TLS.
-
-Dynamic hostname lookup
------------------------
-
-By default, nghttpx performs backend hostname lookup at start up, or
-configuration reload, and keeps using them in its entire session.  To
-make nghttpx perform hostname lookup dynamically, use ``dns``
-parameter in :option:`--backend` option, like so:
-
-.. code-block:: text
-
-   backend=foo.example.com;;dns
-
-nghttpx will cache resolved addresses for certain period of time.  To
-change this cache period, use :option:`--dns-cache-timeout`.
-
-Migration from nghttpx v1.8.0 or earlier
-----------------------------------------
-
-As of nghttpx 1.9.0, ``--frontend-no-tls`` and ``--backend-no-tls``
-have been removed.
-
-To disable encryption on frontend connection, use ``no-tls`` keyword
-in :option:`--frontend` potion:
-
-.. code-block:: text
-
-   frontend=*,3000;no-tls
-
-The TLS encryption is now disabled on backend connection in all modes
-by default.  To enable encryption on backend connection, use ``tls``
-keyword in :option:`--backend` option:
-
-.. code-block:: text
-
-   backend=127.0.0.1,8080;tls
-
-As of nghttpx 1.9.0, ``--http2-bridge``, ``--client`` and
-``--client-proxy`` options have been removed.  These functionality can
-be used using combinations of options.
-
-Use following option instead of ``--http2-bridge``:
-
-.. code-block:: text
-
-   backend=<ADDR>,<PORT>;;proto=h2;tls
-
-Use following options instead of ``--client``:
-
-.. code-block:: text
-
-   frontend=<ADDR>,<PORT>;no-tls
-   backend=<ADDR>,<PORT>;;proto=h2;tls
-
-Use following options instead of ``--client-proxy``:
-
-.. code-block:: text
-
-   http2-proxy=yes
-   frontend=<ADDR>,<PORT>;no-tls
-   backend=<ADDR>,<PORT>;;proto=h2;tls
-
-We also removed ``--backend-http2-connections-per-worker`` option.  It
-was present because previously the number of backend h2 connection was
-statically configured, and defaulted to 1.  Now the number of backend
-h2 connection is increased on demand.  We know the maximum number of
-concurrent streams per connection.  When we push as many request as
-the maximum concurrency to the one connection, we create another new
-connection so that we can distribute load and avoid delay the request
-processing.  This is done automatically without any configuration.
