title: Dots in URL causes 404 with ASP.NET mvc and IIS
body: <p>I have a project that requires my URLs have dots in the path. For example I may have a URL such as www.example.com/people/michael.phelps</p>
  
  <p>URLs with the dot generate a 404. My routing is fine. If I pass in michaelphelps, without the dot, then everything works. If I add the dot I get a 404 error. The sample site is running on Windows 7 with IIS8 Express. URLScan is not running. </p>
  
  <p>I tried adding the following to my web.config:</p>
  
  <pre><code>&lt;security&gt;
    &lt;requestFiltering allowDoubleEscaping="true"/&gt;
  &lt;/security&gt;
  </code></pre>
  
  <p></p>
  
  <p>Unfortunately that didn't make a difference. I just receive a 404.0 Not Found error. </p>
  
  <p>This is a MVC4 project but I don't think that's relevant. My routing works fine and the parameters I expect are there, until they include a dot.</p>
  
  <p>What do I need to configure so I can have dots in my URL?</p>
