title: redirect user in IIS7 between two folders depending on IP mask
body: <p>Suppose I have <code>Default Web Site</code> and folders in it.</p>
  
  <p>Roughly, the tree would look like this:</p>
  
  <pre><code>|- Server
      |- Default Web Site
          |- folder1
          |- folder2
  </code></pre>
  
  <p>I want to redirect the user to different folders in my website depending on their IP mask.</p>
  
  <p>For example if the user's IP has a pattern of:</p>
  
  <pre><code>- 10.10.10.* IIS has to redirect to "folder1"
  - 11.11.11.* IIS has to redirect to "folder2"
  </code></pre>
  
  <p>Is this possible? If so, then how?</p>
