title: mod_rewrite get remaining query string parameters without matching them in the pattern
body: <p>I am extremely new to RewriteRules so I am not sure if this is possible, is there any way of having my second query string parameter be passed to my RewriteRule without me having to specify it in the RegEx pattern?</p>
  
  <p>The reason I ask is because I would like my URL to display as </p>
  
  <pre><code>http://mysite/Pumps/PumpID01
  </code></pre>
  
  <p>Opposed to</p>
  
  <pre><code>http://mysite.com/pumps/product.php?id=PumpID&amp;s=Category
  </code></pre>
  
  <p>The current rewrite rule I am using is:</p>
  
  <pre><code>RewriteRule ^Pumps/([A-Za-z0-9_-]+)/?$ pumps/product.php?id=$1&amp;s= [NC,L,QSA] 
  </code></pre>
  
  <p>If I specify 's' in the substituion then the page renders correctly. However 's' can be one of an expanding total of categories.</p>
  
  <p>How would I go about passing the value of 's' dynamically?</p>
