title: Force lower case of URLs - Override previous rules
body: <p>I have inherited a rather scary looking .htaccess file that is filled with previous rules.  What I am trying to do is simply make every single URL lowercase for SEO reasons.  Currently Google Webmasters is complaining about duplicate pages. eg: www.example.com/AbC1.php has the same content as www.example.com/abc1.php.  To solve this I placed the following lines into my vhosts.conf</p>
  
  <pre><code>#Make URL's lower case
  RewriteEngine On
  RewriteMap lowercase int:tolower
  RewriteCond \$1 [A-Z]
  RewriteRule ^/(.*)$ /\${lowercase:\$1} [R=301,L]
  </code></pre>
  
  <p>But due to one of the many rules I have in my .htaccess file this rule isn't working.  Can I add that above rule and ensure that it overrides any other rules?</p>
