How can I handle winsock..?

I want to develop a program for IP redirection.

Some of famous Internet program haven't proxy setting configuration.

I want to used those programs with my proxy setting.

So, I need to redirect IP when those program send request to their parent site.

I try to used some of WinSock API to handle the winsock. I could know winsock's

status when a program is using winsock and opening port. But I don't know how to handle to redirect IP to my proxy server.

Can anybody help me please..?
