title: can't download file from asp.net application
body: <p>I have an asp.net application that writes some physical files in a folder of the server. </p>
  
  <p>While I work in my test environment I can download the files clicking on the dynamical links, but after I deployed the application I can't download the files anymore.</p>
  
  <p>I'm getting the standard - <code>The page cannot be found error page</code>.</p>
  
  <p>Also I can download the file after I add an extension, like this 
  <code>server/TempFiles/1b008aaa-47ad-4fd7-b95d-05ef81a1785c.txt</code>
  but downloading the file without "<strong>.txt</strong>" is not possible.</p>
  
  <p>How to repair this behavior?</p>
