+ </dd>
+
+ <dt>Discussion</dt>
+ <dd>
+ <p>This example uses an often-overlooked feature of mod_rewrite,
+ by taking advantage of the order of execution of the ruleset. In
+ particular, mod_rewrite evaluates the left-hand-side of the
+ RewriteRule before it evaluates the RewriteCond directives.
+ Consequently, $1 is already defined by the time the RewriteCond
+ directives are evaluated. This allows us to test for the existence
+ of the original (<code>document.html</code>) and target
+ (<code>document.php</code>) files using the same base filename.</p>
+
+ <p>This ruleset is designed to use in a per-directory context (In a
+ &lt;Directory&gt; block or in a .htaccess file), so that the
+ <code>-f</code> checks are looking at the correct directory path.
+ You may need to set a <code class="directive"><a href="../mod/mod_rewite.html#rewritebase">RewriteBase</a></code> directive to specify the
+ directory base that you're working in.</p>

+<h2><a name="canonicalhost" id="canonicalhost">Canonical Hostnames</a></h2>

+
+ <dl>
+ <dt>Description:</dt>
+
+ <dd>The goal of this rule is to force the use of a particular
+ hostname, in preference to other hostnames which may be used to
+ reach the same site. For example, if you wish to force the use
+ of <strong>www.example.com</strong> instead of
+ <strong>example.com</strong>, you might use a variant of the
+ following recipe.</dd>
+
+ <dt>Solution:</dt>
+
+ <dd>
+
+<p>The very best way to solve this doesn't involve mod_rewrite at all,
+but rather uses the <code class="directive"><a href="../mod/alias.html#redirect">Redirect</a></code>
+directive placed in a virtual host for the non-canonical
+hostname(s).</p>
+
+<div class="example"><p><code>
+&lt;VirtualHost *:80&gt;<br />
+<span class="indent">
+ ServerName undesired.example.com<br />
+ ServerAlias example.com notthis.example.com<br />
+<br />
+ Redirect / http://www.example.com/<br />
+</span>
+&lt;/VirtualHost&gt;<br />
+<br />
+&lt;VirtualHost *:80&gt;<br />
+<span class="indent">
+ ServerName www.example.com<br />
+</span>
+&lt;/VirtualHost&gt;
+</code></p></div>
+
+<p>If, for whatever reason, you still want to use <code>mod_rewrite</code>
+- if, for example, you need this to work with a larger set of RewriteRules -
+you might use one of the recipes below.</p>
+
+<p>For sites running on a port other than 80:</p>
+<div class="example"><p><code>
+RewriteCond %{HTTP_HOST} !^www\.example\.com [NC]<br />
+RewriteCond %{HTTP_HOST} !^$<br />
+RewriteCond %{SERVER_PORT} !^80$<br />
+RewriteRule ^/?(.*) http://www.example.com:%{SERVER_PORT}/$1 [L,R,NE]
+</code></p></div>
+
+<p>And for a site running on port 80</p>
+<div class="example"><p><code>
+RewriteCond %{HTTP_HOST} !^www\.example\.com [NC]<br />
+RewriteCond %{HTTP_HOST} !^$<br />
+RewriteRule ^/?(.*) http://www.example.com/$1 [L,R,NE]
+</code></p></div>
+
+ <p>
+ If you wanted to do this generically for all domain names - that
+ is, if you want to redirect <strong>example.com</strong> to
+ <strong>www.example.com</strong> for all possible values of
+ <strong>example.com</strong>, you could use the following
+ recipe:</p>
+
+<div class="example"><p><code>
+RewriteCond %{HTTP_HOST} !^www\. [NC]<br />
+RewriteCond %{HTTP_HOST} !^$<br />
+RewriteRule ^/?(.*) http://www.%{HTTP_HOST}/$1 [L,R,NE]
+</code></p></div>
+
+ <p>These rulesets will work either in your main server configuration
+ file, or in a <code>.htaccess</code> file placed in the <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code> of the server.</p>

+<dt>Description:</dt>
+<dd>You want a single resource (say, a certain file, like index.php) to
+handle all requests that come to a particular directory, except those
+that should go to an existing resource such as an image, or a css file.</dd>
+
+<dt>Solution:</dt>
+<dd>
+<p>As of version 2.2.16, you should use the <code class="directive"><a href="../mod/mod_dir.html#fallbackresource">FallbackResource</a></code> directive for this:</p>
+
+<div class="example"><p><code>
+&lt;Directory /var/www/my_blog&gt;<br />
+<span class="indent">
+ FallbackResource index.php<br />
+</span>
+&lt;/Directory&gt;
+</code></p></div>
+
+<p>However, in earlier versions of Apache, or if your needs are more
+complicated than this, you can use a variation of the following rewrite
+set to accomplish the same thing:</p>
+
+<div class="example"><p><code>
+&lt;Directory /var/www/my_blog&gt;<br />
+<span class="indent">
+ RewriteBase /my_blog<br />
+<br />
+ RewriteCond /var/www/my_blog/%{REQUEST_FILENAME} !-f<br />
+ RewriteCond /var/www/my_blog/%{REQUEST_FILENAME} !-d<br />
+ RewriteRule ^ index.php [PT]<br />
+</span>
+&lt;/Directory&gt;
+</code></p></div>
+
+<p>If, on the other hand, you wish to pass the requested URI as a query
+string argument to index.php, you can replace that RewriteRule with:</p>
+
+<div class="example"><p><code>
+ RewriteRule (.*) index.php?$1 [PT,QSA]
+</code></p></div>
+
+<p>Note that these rulesets can be uses in a <code>.htaccess</code>
+file, as well as in a &lt;Directory&gt; block.</p>
