title: why Application_Error can not handlle some errors?
body: <p>i developed a website(MVC 5) and upload it on a iis7 on a web server.
  i handle errors on method    </p>
  
  <pre><code>protected void Application_Error(){}
  </code></pre>
  
  <p>on the Global.asax.
  yesterday i did some tests on it and i saw when i enter this url</p>
  
  <pre><code>http://www.xxxx.com/.
  </code></pre>
  
  <p>i can get invalid rout on Application_Error method but when i entered that URL with 3dotes or more like this URL</p>
  
  <pre><code>http://www.xxxx.com/...
  </code></pre>
  
  <p>i saw a webpage with this content and Application_Error not works because i have no default page or view with this content on my project.</p>
  
  <pre><code>The page cannot be displayed because an internal server error has occurred.
  </code></pre>
  
  <p>i did some test on another website on the internet and i saw some of theme has the same issue and i think i should do some config on my IIS.</p>
  
  <p>if yes , what config(s) i should set on my IIS and if no what i can do with my project until i can handle it?</p>
