title: IIS 7.5: How to let him serve by default all file extensions (without manually adding them)?
body: <p>It is a little annoying that every time when you put a "new" file-extension on your IIS 7.5 backed server for simple http-download you have to think about adding the extension to the IIS configuration!</p>
  
  <blockquote>
    <p>(e.g. provide a file zipped in the format .7z)</p>
  </blockquote>
  
  <p>Is there a way to tell IIS "serve anything" (like it is the default setting in Apache-Webserver) ?</p>
  
  <p>Thanks</p>
