Re: How to make FASTCGI deliver an external file

I use something very similar from the http server API. It has a function 
like that. Of course I wonder that it users internal http server 
mechanism to do it.

What I'm suggesting here is the same thing (method) for FastCGI !

Yes !

Yes, I need Windows only.

However, it's not a matter of a operating system API call, I guess.

I think it would be a function from FastCGI API. In it's turn, FastCGI 
would call there inside the http server a specific function from this 
http server API.

Isnt it like that ?
