+<h2>HTTP Messaging<a class="headerlink" href="#http-messaging" title="Permalink to this headline">¶</a></h2>
+<p>By default, nghttp2 library checks HTTP messaging rules described in
+<a class="reference external" href="https://tools.ietf.org/html/draft-ietf-httpbis-http2-17#section-8">HTTP/2 specification, section 8</a>.
+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 <a class="reference internal" href="#c.nghttp2_option_set_no_http_messaging" title="nghttp2_option_set_no_http_messaging"><tt class="xref c c-func docutils literal"><span class="pre">nghttp2_option_set_no_http_messaging()</span></tt></a>.</p>
+<p>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 &quot;:scheme&quot;, &quot;:method&quot; and &quot;:path&quot; pseudo
+header fields unless &quot;:method&quot; is not &quot;CONNECT&quot;.  &quot;:authority&quot; is
+optional, but nghttp2 requires either &quot;:authority&quot; or &quot;Host&quot; header
+field must be present.  If &quot;:method&quot; is &quot;CONNECT&quot;, the request headers
+must include &quot;:method&quot; and &quot;:authority&quot; and must omit &quot;:scheme&quot; and
+&quot;:path&quot;.</p>
+<p>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 &quot;:status&quot; pseudo header field containing 3 digits only.</p>
+<p>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 &quot;Host&quot; header field.</p>
+<p>HTTP/2 prohibits connection-specific header fields.  The following
+header fields must not appear: &quot;Connection&quot;, &quot;Keep-Alive&quot;,
+&quot;Proxy-Connection&quot;, &quot;Transfer-Encoding&quot; and &quot;Upgrade&quot;.  Additionally,
+&quot;TE&quot; header field must not include any value other than &quot;trailers&quot;.</p>
+<p>Each header field name and value must obey the field-name and
+field-value production rules described in <a class="reference external" href="https://tools.ietf.org/html/rfc7230#section-3.2">RFC 7230, section
+3.2.</a>.
+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.</p>
+<p>With the above validations, nghttp2 library guarantees that header
+field name passed to <a class="reference internal" href="#c.nghttp2_on_header_callback" title="nghttp2_on_header_callback"><tt class="xref c c-func docutils literal"><span class="pre">nghttp2_on_header_callback()</span></tt></a> is not empty.
+Also required pseudo headers are all present and not empty.</p>
+<p>nghttp2 enforces &quot;Content-Length&quot; validation as well.  All request or
+response headers must not contain more than one &quot;Content-Length&quot;
+header field.  If &quot;Content-Length&quot; 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 &quot;Content-Length&quot;
+header field if it is present (this does not include padding bytes).</p>
+<p>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.</p>

-<p>First we set the number of background threads which run tasks.  By
-default it is set to 1.  In this example, we set it to 16, so at most
-16 tasks can be executed concurrently without blocking handling new
-requests.</p>
-<p>We call <tt class="docutils literal"><span class="pre">req-&gt;run_task()</span></tt> to execute task in background thread.  In
-the passed callback, we just simply sleeps 1 second.  After sleep is
-over, we schedule another callback to send response to the client.
-Since the callback passed to <tt class="docutils literal"><span class="pre">req-&gt;run_task()</span></tt> is executed in the
-different thread from the thread where request callback is called,
-using <tt class="docutils literal"><span class="pre">req</span></tt> or <tt class="docutils literal"><span class="pre">res</span></tt> object directly there may cause undefined
-behaviour.  To avoid this issue, we can use
-<tt class="docutils literal"><span class="pre">nghttp2::asio_http2::channel::post</span></tt> by supplying a callback which
-in turn get called in the same thread where request callback was
-called.</p>
+<p><tt class="docutils literal"><span class="pre">nghttp2::asio_http2::client::session</span></tt> object takes
+<tt class="docutils literal"><span class="pre">boost::asio::io_service</span></tt> object and remote server address.  When
+connection is made, the callback function passed to
+<tt class="docutils literal"><span class="pre">nghttp2::asio_http2::client::on_connect</span></tt> is invoked with connected
+address as its paramter.  After this callback call, use
+<tt class="docutils literal"><span class="pre">nghttp2::asio_http2::session::submit</span></tt> to send request to the
+server.  You can submit multiple requests at once without waiting for
+the completion of previous request.</p>
+<p>The life time of req and res object ends after the callback set by
+<tt class="docutils literal"><span class="pre">nghttp2::asio_http2::server::request::on_close</span></tt> function.
+Application must not use those objects after this call.</p>
+<p>Normally, client does not stop even after all requests are done unless
+connection is lost.  To stop client, call
+<tt class="docutils literal"><span class="pre">nghttp2::asio_http2::server::session::shutdown()</span></tt>.</p>

+<p>The above sample code demonstrates how to enable SSL/TLS and receive
+server push.  Currently,
+<tt class="docutils literal"><span class="pre">nghttp2::asio_http2::client::configure_tls_context</span></tt> function setups
+NPN callbacks for SSL/TLS context for HTTP/2 use.</p>
+<p>To receive server push, use
+<tt class="docutils literal"><span class="pre">nghttp2::asio_http2::client::request::on_push</span></tt> function to set
+callback function which is invoked when server push request is
+arrived.  The callback function takes
+<tt class="docutils literal"><span class="pre">nghttp2::asio_http2::client::request</span></tt> object, which contains the
+pushed request.  To get server push response, set callback using
+<tt class="docutils literal"><span class="pre">nghttp2::asio_http2::client::request::on_response</span></tt>.</p>
+<p>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 <tt class="docutils literal"><span class="pre">nghttp2::asio_http2::client::session::shutdown</span></tt> in this
+example, so the program does not terminate after all responses are
+received.  Hit Ctrl-C to terminate the program.</p>

+<p>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 <tt class="docutils literal"><span class="pre">count</span></tt> object which is shared pointer to int and is
+initialized to 3.  On each request closure (the invocation of the
+callback set by <tt class="docutils literal"><span class="pre">nghttp2::asio_http2::client::request::on_close</span></tt>),
+we decrement the count.  If count becomes 0, we are sure that all
+requests have been done and initiate shutdown.</p>

+<h2>SERVER PUSH<a class="headerlink" href="#server-push" title="Permalink to this headline">¶</a></h2>
+<p>nghttpx supports HTTP/2 server push in default mode.  nghttpx looks
+for Link header field (<a class="reference external" href="http://tools.ietf.org/html/rfc5988">RFC 5988</a>) in response headers from
+backend server and extracts URI-reference with parameter
+<tt class="docutils literal"><span class="pre">rel=preload</span></tt> (see <a class="reference external" href="http://w3c.github.io/preload/#interoperability-with-http-link-header">preload</a>)
+and pushes those URIs to the frontend client. Here is a sample Link
+header field to initiate server push:</p>
+<div class="highlight-http"><div class="highlight"><pre>Link: &lt;/fonts/font.woff&gt;; rel=preload
+Link: &lt;/css/theme.css&gt;; rel=preload
+</pre></div>
+</div>
+<p>Currently, the following restrictions are applied for server push:</p>
+<ol class="arabic simple">
+<li>URI-reference must not contain authority.  If it exists, it is not
+pushed.  <tt class="docutils literal"><span class="pre">/fonts/font.woff</span></tt> and <tt class="docutils literal"><span class="pre">css/theme.css</span></tt> are eligible to
+be pushed.  <tt class="docutils literal"><span class="pre">https://example.org/fonts/font.woff</span></tt> and
+<tt class="docutils literal"><span class="pre">//example.org/css/theme.css</span></tt> are not.</li>
+<li>The associated stream must have method &quot;GET&quot; or &quot;POST&quot;.  The
+associated stream's status code must be 200.</li>
+</ol>
+<p>These limitations may be loosened in the future release.</p>

+<p>nghttpx supports UNIX domain socket with a filename for both frontend
+and backend connections.</p>
+<p>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.</p>
