title: Setting HTTP_X_FORWARDED_FOR server variable in classic ASP
body: <p>I need to set the HTTP_X_FORWARDED_FOR value in the Request.ServerVariables collection. I'm trying with Fiddler (see <a href="https://stackoverflow.com/questions/3211854/how-to-set-value-for-http-x-forwarded-for-manually">this article</a>).</p>
  
  <p>So I set up a custom HTTP request:</p>
  
  <pre><code>GET http://myhost/ HTTP/1.1 http_x_forwarded_for: my.fake.ip.1, my.fake.ip.2 Host: myhost.
  </code></pre>
  
  <p>The request is correctly executed.</p>
  
  <p>But when I debug the code, the Request.ServerVariables("HTTP_X_FORWARDED_FOR") is empty.
  Where am I wrong?
  Is Fiddler the correct tool?</p>
