title: ISAPI Rewrite : Append querystring to the rewrited URl's Query String
body: <p>Actually, using the following ISAPI rule</p>
  
  <pre><code>RewriteCond %{HTTP:Host} ^domain.com$
  RewriteRule ^/Product-name/$ /test.cfm?ProductID=xxxx [NC,L]
  </code></pre>
  
  <p>I'm rewriting the following URL </p>
  
  <pre><code>htttp://www.domain.com/Product-name/
  </code></pre>
  
  <p>to</p>
  
  <pre><code>htttp://www.domain.com/test.cfm?ProducID=xxxx
  </code></pre>
  
  <p>This is working fine, But when I use the querystring in URL, it is not working</p>
  
  <p>For Egs:
  The following URL is not working</p>
  
  <pre><code>htttp://www.domain.com/Product-name?categoryID=YYYY
  </code></pre>
  
  <p>I need to rewrite the above URL as follows</p>
  
  <pre><code>htttp://www.domain.com/test.cfm?ProducID=xxxx&amp;categoryID=YYYY
  </code></pre>
  
  <p>I've used the following rule, but no luck</p>
  
  <pre><code>RewriteCond %{QUERY_STRING} ^param=(\d+)$ [NC] 
  RewriteRule ^/Product-name/$ /test.cfm?ProductID=xxxx?param2=%1? [NC,L]
  </code></pre>
  
  <p>So is there any solution for this?</p>
