title: mod_rewrite single "directory" retain the rest of the URL vars
body: <p>Can I have a single URL var get aliased to a directory, then any additional URL variables stay in the string?</p>
  
  <p>Example:
  If I have a contact page and want to swap the "regarding" select based on a quick URL variable.</p>
  
  <p>?page=contact => loads the contact page with all defaults</p>
  
  <p>?page=contact&amp;regarding=bug => loads the contact with the regarding select option for a bug report automatically selected</p>
  
  <pre><code>#Enable rewrite engine
  RewriteEngine On
  #contact,contact/ -&gt; page=contact
  RewriteRule ^contact?$ ?page=contact [L]
  RewriteRule ^contact/?$ ?page=contact [L]
  </code></pre>
  
  <p>This works fine for domain/contact/, but if I add additional URL variables they get dropped, even if they appear in the URL.</p>
  
  <p>I understand I could do something like:</p>
  
  <pre><code>RewriteRule ^contact/bug/?$ ?page=contact&amp;regarding=bug [L]
  </code></pre>
  
  <p>but I would rather have it accept any number of flags in case I wanted to do extra stuff there.</p>
  
  <p>I would like to be able to have domain.com/contact/ and domain.com/contact/?regarding=bug </p>
