title: Can't Get Fiddler to Capture local traffic to IIS
body: <p>I have recently installed the latest Fiddler (Fiddler4) and absolutely nothing that I try is working to get it to capture local traffic.  I have an MVC application that is connecting to an MVC WebApi app both running on IIS, here's what I've tried:</p>
  
  <ul>
  <li>Fiddler Options > Connections > Monitor All Connections &amp; Use PAC Script</li>
  <li>Changed the WebClient C# call to use the following URLs with no success:
  <ul>
  <li><code>http://machinename/app-name</code></li>
  <li><code>http://localhostproxy.com/app-name</code></li>
  <li>all of the ipv4 / ipv6 etc urls on this page <a href="http://fiddler2.com/documentation/Configure-Fiddler/Tasks/MonitorLocalTraffic">http://fiddler2.com/documentation/Configure-Fiddler/Tasks/MonitorLocalTraffic</a></li>
  <li>also tried using the . fix - <code>http://localhost</code>.</li>
  </ul></li>
  <li>Changed my "Default Website" in IIS to run under a new AppPool that uses my local account, and ran Fiddler as administrator</li>
  <li>added <code>
  &lt;system.net&gt;
      &lt;defaultProxy&gt;
        &lt;proxy bypassonlocal="False" usesystemdefault="True" /&gt;
      &lt;/defaultProxy&gt;
    &lt;/system.net&gt;
  </code> to my web.config of the MVC app.</li>
  </ul>
  
  <p>Nothing has worked, I have no idea what to try.  Any advice is greatly appreciated.
  Thanks,
  Shawn</p>
