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> + +<div class="example"><p><code> +RewriteEngine on<br /> +RewriteBase /products/<br /> +RewriteRule ^<strong>widget/</strong>(.*)$ <strong>http://product.example.com/widget/</strong>$1 [<strong>P</strong>]<br /> +ProxyPassReverse /products/widget/ http://product.example.com/widget/ +</code></p></div> + + <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> + +<div class="example"><p><code> +RewriteCond %{REQUEST_FILENAME} <strong>!-f</strong><br /> +RewriteCond %{REQUEST_FILENAME} <strong>!-d</strong><br /> +RewriteRule ^/(.*) http://<strong>old</strong>.example.com/$1 [<strong>P</strong>]<br /> +ProxyPassReverse / http://old.example.com/ +</code></p></div> + </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_rewrite.html#proxypassmatch">ProxyPassMatch</a></code> whenever possible in + preference to mod_rewrite.</p> + </dd> + </dl> + +</div></div> +<div class="bottomlang"> +<p><span>Available Languages: </span><a href="../en/rewrite/proxy.html" title="English"> en </a></p> +</div><div id="footer"> +<p class="apache">Copyright 2011 The Apache Software Foundation.<br />Licensed under the <a href="http://www.apache.org/licenses/LICENSE-2.0">Apache License, Version 2.0</a>.</p> +<p class="menu"><a href="../mod/">Modules</a> | <a href="../mod/directives.html">Directives</a> | <a href="../faq/">FAQ</a> | <a href="../glossary.html">Glossary</a> | <a href="../sitemap.html">Sitemap</a></p></div> +</body></html>
