Sometimes you need to serve a file that has no extension because the program that creates the file doesn’t set an extension. This is handy when trying to serve a file from EasyPal by Erik VK4AES.
Use the following web.config to allow the file to be served and its content to be interpreted by the browser after its downloaded:
<?xml version="1.0" encoding="UTF-8"?>
<mimeMap fileExtension="." mimeType="*/*" />
