This has a negative impact on performance, but is necessary in order to provide a common interface for both HTTP/1.1 and HTTP/2 (as well as future HTTP versions).</p> +<p>It is still possible to use a single process per connection, and avoid the creation of additional processes for each request, by implementing a stream handler to process the requests. This can be done for all requests, or just for a single endpoint depending on the application's needs.</p> +<p>Stream handlers provide an asynchronous interface and must not block, so the implementation will be very different from normal Cowboy handlers, but the performance gains are important enough to justify it in some cases.</p> + + + + + + + + + + + + <nav style="margin:1em 0"> + + <a style="float:left" href="https://ninenines.eu/docs/en/cowboy/2.8/guide/middlewares/"> + Middlewares + </a> + + + + <a style="float:right" href="https://ninenines.eu/docs/en/cowboy/2.8/guide/migrating_from_2.7/"> + Migrating from Cowboy 2.7 to 2.8 + </a> + + </nav> + + + + +</div> + +<div class="span3 sidecol"> + + +<h3> + Cowboy + 2.8 + + User Guide +</h3> + +<ul> + + <li><a href="/docs/en/cowboy/2.8/guide">User Guide</a></li> + + + <li><a href="/docs/en/cowboy/2.8/manual">Function Reference</a></li> + + +</ul> + +<h4 id="docs-nav">Navigation</h4> + +<h4>Version select</h4> +<ul> + + + + <li><a href="/docs/en/cowboy/2.8/guide">2.8</a></li> + + <li><a href="/docs/en/cowboy/2.7/guide">2.7</a></li> + + <li><a href="/docs/en/cowboy/2.6/guide">2.6</a></li> + + <li><a href="/docs/en/cowboy/2.5/guide">2.5</a></li> + + <li><a href="/docs/en/cowboy/2.4/guide">2.4</a></li> + + <li><a href="/docs/en/cowboy/2.3/guide">2.3</a></li> + +</ul> + +<h3 id="_like_my_work__donate">Like my work?
