title: IIS7 Rewrite Map Regex?
body: <p>Is it possible to use reg ex in a rewrite map? For example:</p>
  
  <pre><code>&lt;rewriteMap name="Redirects"&gt;
     &lt;add key="/blah/(.*)" value="/blah/{R:1}" /&gt;
  &lt;/rewriteMap&gt;
  </code></pre>
  
  <p>Or is there a way to handle this approach? Currently, I have a rule set up to match on everything and then use the rewrite map to map to new urls. I would like to capture everything under a directory e.g. resource files (blah)... without having to manually to do this for them all.</p>
