+<div class="paragraph"><p>This function reads the request body and parses it as
+multipart. Each parts of a multipart representation have
+their own headers and body. This function parses and returns
+headers. Examples of multipart media types are
+<code>multipart/form-data</code> and <code>multipart/byteranges</code>.</p></div>
+<div class="paragraph"><p>Cowboy will skip any data remaining until the beginning of
+the next part. This includes the preamble to the multipart
+message but also the body of a previous part if it hasn&#8217;t
+been read. Both are skipped automatically when calling this
+function.</p></div>
+<div class="paragraph"><p>Cowboy will read the body before parsing in chunks of size
+up to 64KB, with a period of 5 seconds. This is tailored for
+reading part headers and might not be the most efficient for
+skipping the previous part&#8217;s body.</p></div>
+<div class="paragraph"><p>The headers returned are MIME headers, <strong>NOT</strong> HTTP headers.
+They can be parsed using the functions from the <code>cow_multipart</code>
+module. In addition, the <code>cow_multipart:form_data/1</code> function
+can be used to quickly extract information from <code>multipart/form-data</code>
+representations.</p></div>

+related to a stream. Exceptions vary depending on the

-<div class="paragraph"><p>The <code>init/2</code> callback is common to all handlers. To upgrade

-<code>init/2</code> function, as the Req object will not be available
-after it returns. Websocket sub-protocol selection should
-therefore be done in this function.</p></div>
-<div class="paragraph"><p>The optional <code>websocket_init/1</code> callback will be called once

-to perform any required initialization of the handler.</p></div>
-<div class="paragraph"><p>Note that the <code>init/2</code> function does not run in the same
-process as the Websocket callbacks. Any Websocket-specific
-initialization must be done in <code>websocket_init/1</code>.</p></div>

-frame received. The <code>websocket_info/2</code> callback will be
-called for every Erlang message received.</p></div>

-tuple).</p></div>
-<div class="paragraph"><p>The optional <code>terminate/3</code> callback will ultimately be called
-with the reason for the termination of the connection. This
-callback is common to all handlers. Note that Websocket has
-no concept of requests so it sets the second argument to
-undefined.</p></div>
-<div class="paragraph"><p>Cowboy will terminate the process right after closing the
-Websocket connection. This means that there is no need to
-perform any cleanup in the <code>terminate/3</code> callback.</p></div>

-connections:</p></div>
