Redirect a single file using IIS

I ended it finding it on my own. It was easy after I found the "Switch to Feature View" context menu in IIS Manager.

1. If you don't have HTTP Redirection installed you'll have to install it. From the Control Panel select "Turn Windows Features on or off", then browse to Internet Information Services > World Wide Web Services > Common HTTP Features and select HTTP Redirection;
2. Boot up IIS Manager (inetmgr.exe);
3. Browse for your file (you may have to change to Content View to see it);
4. Right-click the file and select "Switch to Feature View". The file now appears in the Connections tree.
5. Select the file in the Connections tree, then double-click "HTTP Redirect";
6. Select "Redirect requests to this destination" and enter the address to redirect to.

does this help?

if I understand correctly, you are trying to set up a 301 Redirect for a single file?
