title: Url Rewrite in IIS 7.5 causes Internal server error
body: <p>I have a web application runs @ Windows 2008 R2, ASP.NET v4.0.</p>
  
  <p>I installed the Url Rewrite Module, and started to use it as shown in the official examples.</p>
  
  <p>My problem starts when the <code>&lt;rewrite&gt;</code> tag is added to the web.config under <code>&lt;system.webServer&gt;</code> - actually when I try to browse to any page under this current application, I get <code>500 - Internal server error</code>.</p>
  
  <p>This is the <code>&lt;rewrite&gt;</code> block I've been adding:</p>
  
  <pre><code>&lt;system.webServer&gt;
      &lt;rewrite&gt;
          &lt;rules&gt;
              &lt;rule name="test1"&gt;
                  &lt;match url="^default/([0-9]+)/([_0-9a-z-]+)" /&gt;
                  &lt;action type="Rewrite" url="default.aspx?id={R:1}&amp;amp;title={R:2}" /&gt;
              &lt;/rule&gt;
          &lt;/rules&gt;
      &lt;/rewrite&gt;
  &lt;/system.webServer&gt;
  </code></pre>
