+operations available to them.</p></div>
+<div class="sect1">
+<h2 id="_http_1_1">HTTP/1.1</h2>
+<div class="sectionbody">
+<div class="paragraph"><p>HTTP/1.1 is a text request-response protocol. The client
+sends a request, the server sends back a response.</p></div>
+<div class="paragraph"><p>Gun provides convenience functions for performing GET, HEAD,
+OPTIONS, POST, PATCH, PUT, and DELETE requests. All these
+functions are aliases of <code>gun:request/{4,5}</code> for each respective
+methods. Gun also provides a <code>gun:data/4</code> function for streaming
+the request body.</p></div>
+<div class="paragraph"><p>Gun will send a <code>gun_response</code> message for every response
+received, followed by zero or more <code>gun_data</code> messages for
+the response body. If something goes wrong, a <code>gun_error</code>
+will be sent instead.</p></div>
+<div class="paragraph"><p>Gun provides convenience functions for dealing with messages.
+The <code>gun:await/{2,3,4}</code> function waits for a response to the given
+request, and the <code>gun:await_body/{2,3,4}</code> function for the
+response’s body. The <code>gun:flush/1</code> function can be used to clear all
+messages related to a request or a connection from the mailbox
+of the process.</p></div>
+<div class="paragraph"><p>The function <code>gun:cancel/2</code> can be used to silence the
+response to a request previously sent if it is no longer
+needed. When using HTTP/1.1 there is no multiplexing so
+Gun will have to receive the response fully before any
+other response can be received.</p></div>
+<div class="paragraph"><p>Finally, Gun can upgrade an HTTP/1.1 connection to Websocket.
+It provides the <code>gun:ws_upgrade/{2,3,4}</code> function for that
+purpose. A <code>gun_ws_upgrade</code> message will be sent on success;
+a <code>gun_response</code> message otherwise.</p></div>
+</div>
+</div>
+<div class="sect1">
+<h2 id="_spdy">SPDY</h2>
+<div class="sectionbody">
+<div class="paragraph"><p>SPDY is a binary protocol based on HTTP, compatible with
+the HTTP semantics, that reduces the complexity of parsing
+requests and responses, compresses the HTTP headers and
+allows the server to push multiple responses to a single
+request.</p></div>
+<div class="paragraph"><p>The SPDY interface is very similar to HTTP/1.1, so this
+section instead focuses on the differences in the interface
+for the two protocols.</p></div>
+<div class="paragraph"><p>Because a SPDY server can push multiple responses to a
+single request, Gun might send <code>gun_push</code> messages for
+every push received. They can be ignored safely if they
+are not needed.</p></div>
+<div class="paragraph"><p>The <code>gun:cancel/2</code> function will use the SPDY stream
+cancellation mechanism which allows Gun to inform the
+server to stop sending a response for this particular
+request, saving resources.</p></div>
+<div class="paragraph"><p>It is not possible to upgrade a SPDY connection to Websocket
+due to protocol limitations.</p></div>
+</div>
+</div>
+<div class="sect1">
+<h2 id="_websocket">Websocket</h2>
+<div class="sectionbody">
+<div class="paragraph"><p>Websocket is a binary protocol built on top of HTTP that
+allows asynchronous concurrent communication between the
+client and the server. A Websocket server can push data to
+the client at any time.</p></div>
+<div class="paragraph"><p>Websocket is only available as a connection upgrade over
+an HTTP/1.1 connection.</p></div>
+<div class="paragraph"><p>Once the Websocket connection is established, the only
+operation available on this connection is sending Websocket
+frames using <code>gun:ws_send/2</code>.</p></div>
+<div class="paragraph"><p>Gun will send a <code>gun_ws</code> message for every frame received.</p></div>
+</div>
+</div>
+<div class="sect1">
+<h2 id="_summary">Summary</h2>
+<div class="sectionbody">
+<div class="paragraph"><p>The two following tables summarize the supported operations
+and the messages Gun sends depending on the connection’s
+current protocol.</p></div>
