title: URL Rewrite regex, can't seem to get it to not force the include of www.'s
body: <p>I've got the Hellicon Tech URL rewrite ISAPI filter on my server. I've got a global file that dictates the settings across the server with the following.</p>
  
  <pre><code>RewriteCond %{HTTPS} (on)?
  RewriteCond %{HTTP:Host} ^(?!www\.)(.+)$ [NC]
  RewriteCond %{REQUEST_URI} (.+)
  RewriteRule .? http(?%1s)://www.%2%3 [R=301,L]
  </code></pre>
  
  <p>Basically it forces any request coming to the site to apply a "www." to prefix the URL that's being requested.</p>
  
  <p>I've created a specific set of rules for a site on my server, but each time I attempt to modify the pattern to not force the www.'s it either breaks simply doesn't work.</p>
  
  <p>I've narrowed this down to being specifically around the regular expressions, however I cant' seem to get it right.</p>
  
  <p>Any suggestions on making this work would be greatly appreciated, still wanting to keep the https if the domain is requiring it, but trying to eliminate the www. prefix wont seem to work.</p>
