I'd like to start off by saying this is a great site you have here. They tools alone are a really great collection.

You have many tools for acting as a proxy for existing applications however, I am interested in learning how to use proxies from an application in which I have the source. The only source I found on your site that uses proxies are all HTTP based, which my understanding is nothing more than a set of headers sent to the proxy to forward the HTTP request. For non HTTP protocols, would I strictly be using SOCKS? Would you be able to point me in the right direction as to where I could read more about/see some code using proxies in C on a windows platform?

Thanks for your time.

the existent proxy types are:
- http proxy: works only with the http protocol
- http connect proxy: like the above one but covers also any other tcp protocol (imagine tcp data encapsulated in a http protocol), that's why without the "connect" method enabled is not possible to use the ssl layer of the https websites
- socks 4/5: any tcp protocol
- socks 5+udp: any tcp and udp protocol

personally I have never used the socks libraries so I don't have an exact one to suggest.
if you want to implement the protocol by hand you need to check the related rfc documents or at least http://en.wikipedia.org/wiki/SOCKS and also the source code of proxymini is very useful to understand it
