Question

Is it possible to create an HTTP tunnel in Delphi or C++?

My application connects to several HTTP servers that do not belong to the company I work for. Because of that, our users need to open their firewall ports to allow those connections. I thought about creating a tunnel at my company and redirecting HTTP requests made by my application through this tunnel. This way, my clients will only need to open one port and the tunnel will handle all requests. All requests are made with POST or GET using indy components.

EDIT: I can’t use an HTTP proxy. Some of my users have already got their own HTTP proxy and it is going to be impossible to connect to two different proxy servers at the same time.
