"Friendly URL" function

[gordon01]

What it requires???
I try to use it, but in help I see, that "this function cannot be used on you server".
I'm using a virtual hosting, server running on Apache.
A can ask hoster to enable required functions, but I don't know, what.

It requires that PHP be running as an Apache server module.

Oh, No! On my hosting, php running as cgi. What Can I do?
