title: IIS - "The system cannot find the file specified."
body: <p>I am building an asp.net web application which has been working on local and staging. however, when i deployed to live, there is a little weird issue occurred. below is the live environment details. </p>
  
  <p>live environment:</p>
  
  <ul>
  <li>Server 2003 </li>
  <li>IIS 6</li>
  </ul>
  
  <p>when the request url is below, if page not found, it will redirect to page 404 configured in the IIS.
  "http://www.xxxx.com/folder1/default.aspx"</p>
  
  <p>however, when the request url is below (with a dot in the folder), it will show a IIS default 404 message which is "The system cannot find the file specified." which isn't what i configured in the IIS and it seems like it skips all the http handlers and modules. Therefore, my custom http handler stop working with this kind of url.</p>
  
  <p>"http://www.xxxx.com/folder.1/default.aspx"</p>
  
  <p>My guess it something to do with the IIS setting. i have have several research, there is no other issue like me. </p>
  
  <p>appreciated if anyone can help. Thanks a lot.</p>
