<p>This document supplements the <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code>
<a href="../mod/mod_rewrite.html">reference documentation</a>. It describes
how to use the RewriteRule's [P] flag to proxy content to another server.
A number of recipes are provided that describe common scenarios.</p>

<dl>
    <dt>Description:</dt>

<dd>
    <p>
    mod_rewrite provides the [P] flag, which allows URLs to be passed,
    via mod_proxy, to another server. Two examples are given here. In
    one example, a URL is passed directly to another server, and served
    as though it were a local URL. In the other example, we proxy
    missing content to a back-end server.</p>
    </dd>

<dt>Solution:</dt>

<dd>
      <p>To simply map a URL to another server, we use the [P] flag, as
      follows:</p>

<pre class="prettyprint lang-config">RewriteEngine  on
RewriteBase    "/products/"
RewriteRule    "^widget/(.*)$"  "http://product.example.com/widget/$1"  [P]
ProxyPassReverse "/products/widget/" "http://product.example.com/widget/"</pre>

<p>In the second example, we proxy the request only if we can't find
   the resource locally. This can be very useful when you're migrating
   from one server to another, and you're not sure if all the content
   has been migrated yet.</p>

<pre class="prettyprint lang-config">RewriteCond "%{REQUEST_FILENAME}"       !-f
RewriteCond "%{REQUEST_FILENAME}"       !-d
RewriteRule "^/(.*)" "http://old.example.com/$1" [P]
ProxyPassReverse "/" "http://old.example.com/"</pre>

</dd>

<dt>Discussion:</dt>

<dd><p>In each case, we add a <code class="directive"><a href="../mod/mod_proxy.html#proxypassreverse">ProxyPassReverse</a></code> directive to ensure
    that any redirects issued by the backend are correctly passed on to
    the client.</p>

<p>Consider using either <code class="directive"><a href="../mod/mod_proxy.html#proxypass">ProxyPass</a></code> or <code class="directive"><a href="../mod/mod_proxy.html#proxypassmatch">ProxyPassMatch</a></code> whenever possible in
    preference to mod_rewrite.</p>
