title: Replacing GET variables names with slash
body: <p>I have URL like <a href="http://www.blah.eu/cats/black_cats?age=over-10-years&amp;sex=male" rel="nofollow">http://www.blah.eu/cats/black_cats?age=over-10-years&amp;sex=male</a> and I would like to parse it into <a href="http://www.blah.eu/cats/black_cats/over-10-years/male" rel="nofollow">http://www.blah.eu/cats/black_cats/over-10-years/male</a> without losing $_GET information (for PHP to be able to parse it, basically.
  My current .htaccess looks like</p>
  
  <pre><code>RewriteEngine On
  RewriteCond %{HTTP_HOST} !^www\.
  RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME}.php -f
  RewriteRule (.*) $1.php [L]
  </code></pre>
  
  <p>Is it in any way possible? Unfortunately I am not yet familiar with Apache servers.</p>
