It's free, it's one-hundred percent compatible with Apache's own REQUEST_URI, and best of all, it's guaranteed to work no matter what. REQUEST_URI for Windows gets whatever the user entered into the address bar – period. Nothing more, nothing less. And of course, you never have to modify a single script to make them work, this does all the work for you!
