title: IIRF URL rewrite to force www prefix: example.com -> www.example.com
body: <p>I'm trying to do something pretty simple in iirf.  </p>
  
  <p>I want all requests that are missing the www. prefix to have it added.</p>
  
  <p>This is my IsapiRewrite4.ini:</p>
  
  <pre><code>RewriteCond %{HTTP_HOST} ^example\.com$ [I]
  RewriteRule ^(.*)$ www.example.com/$1 [R=301,L]
  </code></pre>
  
  <p>This is my SampleUrls.txt:</p>
  
  <pre><code>example.com
  example.com/grants
  www.example.com
  www.example.com/grants
  </code></pre>
  
  <p>I place the files in the same directory as TestDriver.exe, and run testdriver -d .
  All the tests are ignored:</p>
  
  <pre><code>NO ACTION 'example.com' ==&gt; --
  
  NO ACTION 'example.com/grants' ==&gt; --
  
  NO ACTION 'www. example.com' ==&gt; --
  
  NO ACTION 'www. example.com/grants' ==&gt; --
  </code></pre>
  
  <p>Thanks,</p>
  
  <p>Ashley</p>
