  36 <h3>Summary</h3>
  37
  38     <p>This module <em>requires</em> the service of <code class="module"><a href="../mod/mod_proxy.html">mod_proxy</a></code>. It provides the features used for
  39     proxying HTTP/2 requests. <code class="module"><a href="../mod/mod_proxy_http2.html">mod_proxy_http2</a></code>
  40     supports HTTP/2 only. It does <em>not</em>
  41     provide any downgrades to HTTP/1.1.</p>
  42
  43     <p>Thus, in order to get the ability of handling HTTP/2 proxy requests,
  44     <code class="module"><a href="../mod/mod_proxy.html">mod_proxy</a></code> and <code class="module"><a href="../mod/mod_proxy_http2.html">mod_proxy_http2</a></code>
  45     have to be present in the server.</p>
  46
  47     <p><code class="module"><a href="../mod/mod_proxy_http2.html">mod_proxy_http2</a></code> works with incoming requests
  48     over HTTP/1.1 and HTTP/2 requests. If <code class="module"><a href="../mod/mod_proxy_http2.html">mod_proxy_http2</a></code>
  49     handles the frontend connection, requests against the same HTTP/2
  50     backend are sent over a single connection, whenever possible.</p>
  51
  52     <p>This module relies on <a href="http://nghttp2.org/">libnghttp2</a>
  53     to provide the core http/2 engine.</p>

  55     <div class="warning"><h3>Warning</h3>
