<h2><a name="old-to-new" id="old-to-new">From Old to New (internal)</a></h2>
<dl>
<dt>Description:</dt>
<dd>
<p>Assume we have recently renamed the page
<code>foo.html</code> to <code>bar.html</code> and now want
to provide the old URL for backward compatibility. However,
we want that users of the old URL even not recognize that
the pages was renamed - that is, we don't want the address to
change in their browser.</p>
</dd>
<dt>Solution:</dt>
<dd>
<p>We rewrite the old URL to the new one internally via the
following rule:</p>
<div class="example"><p><code>
RewriteEngine on<br />
RewriteRule ^<strong>/old</strong>\.html$ <strong>/new</strong>.html [PT]
</code></p></div>
</dd>

<h2><a name="old-to-new-extern" id="old-to-new-extern">Rewriting From Old to New (external)</a></h2>
<dl>
<dt>Description:</dt>
<dd>
<p>Assume again that we have recently renamed the page
<code>foo.html</code> to <code>bar.html</code> and now want
to provide the old URL for backward compatibility. But this
time we want that the users of the old URL get hinted to
the new one, i.e. their browsers Location field should
change, too.</p>
</dd>
<dt>Solution:</dt>
<dd>
<p>We force a HTTP redirect to the new URL which leads to a
change of the browsers and thus the users view:</p>
<div class="example"><p><code>
RewriteEngine on<br />
RewriteRule ^<strong>/foo</strong>\.html$ <strong>bar</strong>.html [<strong>R</strong>]
</code></p></div>
</dd>
<dt>Discussion</dt>
<dd>
<p>In this example, as contrasted to the <a href="#old-to-new-intern">internal</a> example above, we can simply
use the Redirect directive. mod_rewrite was used in that earlier
example in order to hide the redirect from the client:</p>
<div class="example"><p><code>
Redirect /foo.html /bar.html
</code></p></div>
</dd>
</dl>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>

<dl>
<dt>Description:</dt>
<dd>
<p>If a resource has moved to another server, you may wish to have
URLs continue to work for a time on the old server while people
update their bookmarks.</p>
</dd>
<dt>Solution:</dt>
<dd>
<p>You can use <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> to redirect these URLs
to the new server, but you might also consider using the Redirect
or RedirectMatch directive.</p>
<div class="example"><h3>With mod_rewrite</h3><p><code>
RewriteEngine on<br />
RewriteRule ^/docs/(.+) http://new.example.com/docs/$1 [R,L]

<dt>Description:</dt>
<dd>
<p>How can we transform a static page
<code>foo.html</code> into a dynamic variant
<code>foo.cgi</code> in a seamless way, i.e. without notice
by the browser/user.</p>
</dd>
<dt>Solution:</dt>
<dd>
<p>We just rewrite the URL to the CGI-script and force the
handler to be <strong>cgi-script</strong> so that it is
executed as a CGI program.
This way a request to <code>/~quux/foo.html</code>
internally leads to the invocation of
<code>/~quux/foo.cgi</code>.</p>
<div class="example"><p><code>
RewriteEngine on<br />
RewriteBase /~quux/<br />

<h2><a name="backward-compatibility" id="backward-compatibility">Backward Compatibility for file extension change</a></h2>
<dl>
<dt>Description:</dt>
<dd>
<p>How can we make URLs backward compatible (still
existing virtually) after migrating <code>document.YYYY</code>
to <code>document.XXXX</code>, e.g. after translating a
bunch of <code>.html</code> files to <code>.php</code>?</p>
</dd>
<dt>Solution:</dt>
<dd>
<p>We rewrite the name to its basename and test for
existence of the new extension. If it exists, we take
that name, else we rewrite the URL to its original state.</p>
<div class="example"><p><code>
# backward compatibility ruleset for<br />
# rewriting document.html to document.php<br />
# when and only when document.php exists<br />
<Directory /var/www/htdocs><br />
<span class="indent">
RewriteEngine on<br />
RewriteBase /var/www/htdocs<br />
<br />
RewriteCond $1.php -f<br />
RewriteCond $1.html !-f<br />
RewriteRule ^(.*).html$ $1.php<br />
</span>
</Directory>
</code></p></div>
</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
<Directory> 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_rewrite.html#rewritebase">RewriteBase</a></code> directive to specify the
directory base that you're working in.</p>
</dd>
</dl>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<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/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>
<VirtualHost *:80><br />
<span class="indent">
ServerName undesired.example.com<br />
ServerAlias example.com notthis.example.com<br />
<br />
Redirect / http://www.example.com/<br />
</span>
</VirtualHost><br />
<br />
<VirtualHost *:80><br />
<span class="indent">
ServerName www.example.com<br />
</span>
</VirtualHost>
</code></p></div>
<p>You can alternatively accomplish this using the
<code class="directive"><a href="../mod/core.html#if"><If></a></code>
directive:</p>
<div class="example"><p><code>
<If "%{HTTP_HOST} != 'www.example.com'"><br />
<span class="indent">
Redirect / http://www.example.com/
</span>
</If>
</code></p></div>
<p>Or, for example, to redirect a portion of your site to HTTPS, you
might do the following:</p>
<div class="example"><p><code>
<If "%{SERVER_PROTOCOL} != 'HTTPS'"><br />
<span class="indent">
Redirect /admin/ https://www.example.com/admin/
</span>
</If>
</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 />

<dd>
<p>We wish to provide different content based on the browser, or
user-agent, which is requesting the content.</p>
</dd>
<dt>Solution:</dt>
<dd>
<p>We have to decide, based on the HTTP header "User-Agent",
which content to serve. The following config
does the following: If the HTTP header "User-Agent"
contains "Mozilla/3", the page <code>foo.html</code>
is rewritten to <code>foo.NS.html</code> and the
rewriting stops. If the browser is "Lynx" or "Mozilla" of
version 1 or 2, the URL becomes <code>foo.20.html</code>.
All other browsers receive page <code>foo.32.html</code>.
This is done with the following ruleset:</p>
<div class="example"><p><code>
RewriteCond %{HTTP_USER_AGENT} ^<strong>Mozilla/3</strong>.*<br />
RewriteRule ^foo\.html$ foo.<strong>NS</strong>.html [<strong>L</strong>]<br />

<h2><a name="canonicalurl" id="canonicalurl">Canonical URLs</a></h2>
<dl>
<dt>Description:</dt>
<dd>
<p>On some webservers there is more than one URL for a
resource. Usually there are canonical URLs (which are be
actually used and distributed) and those which are just
shortcuts, internal ones, and so on. Independent of which URL the
user supplied with the request, they should finally see the
canonical one in their browser address bar.</p>
</dd>
<dt>Solution:</dt>
<dd>
<p>We do an external HTTP redirect for all non-canonical
URLs to fix them in the location view of the Browser and
for all subsequent requests. In the example ruleset below
we replace <code>/puppies</code> and <code>/canines</code>
by the canonical <code>/dogs</code>.</p>
<div class="example"><p><code>
RewriteRule ^/(puppies|canines)/(.*) /dogs/$2 [R]
</code></p></div>
</dd>
<dt>Discussion:</dt>

This should really be accomplished with Redirect or RedirectMatch
directives:

RedirectMatch ^/(puppies|canines)/(.*) /dogs/$2

<h2><a name="moveddocroot" id="moveddocroot">Moved <code>DocumentRoot</code></a></h2>
<dl>
<dt>Description:</dt>
<dd>
<p>Usually the <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code>
of the webserver directly relates to the URL "<code>/</code>".
But often this data is not really of top-level priority. For example,
you may wish for visitors, on first entering a site, to go to a
particular subdirectory <code>/about/</code>. This may be accomplished
using the following ruleset:</p>
</dd>
<dt>Solution:</dt>
<dd>
<p>We redirect the URL <code>/</code> to
<code>/about/</code>:
</p>
<div class="example"><p><code>
RewriteEngine on<br />
RewriteRule <strong>^/$</strong> /about/ [<strong>R</strong>]
</code></p></div>
<p>Note that this can also be handled using the <code class="directive"><a href="../mod/mod_alias.html#redirectmatch">RedirectMatch</a></code> directive:</p>
<div class="example"><p><code>
RedirectMatch ^/$ http://example.com/about/
</code></p></div>
<p>Note also that the example rewrites only the root URL. That is, it
rewrites a request for <code>http://example.com/</code>, but not a
request for <code>http://example.com/page.html</code>. If you have in
fact changed your document root - that is, if <strong>all</strong> of
your content is in fact in that subdirectory, it is greatly preferable
to simply change your <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code>
directive, or move all of the content up one directory,
rather than rewriting URLs.</p>

<h2><a name="fallback-resource" id="fallback-resource">Fallback Resource</a></h2>
<dl>
<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>
<Directory /var/www/my_blog><br />
<span class="indent">
FallbackResource index.php<br />
</span>
</Directory>
</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>
<Directory /var/www/my_blog><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>
</Directory>
</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 used in a <code>.htaccess</code>
file, as well as in a <Directory> block.</p>
