Forwarding outgoing connections in C ++

Question

Is there any way in C ++ for Windows to monitor a program and redirect any outgoing requests that it makes on a particular port? I have a simple C ++ http proxy and want it to be able to automatically redirect all browser requests to port 80 through itself.

Answer 1

An easy way to do this is to create a Windows kernel to capture socket requests and redirect them to your proxy.

Some useful documentation on this subject:
