I'm needing to write a proxy. I'm going to use it on the network to filter web content. I'll be writing this in vb.net and I've played around with some simple examples but they don't seem to be working correctly.
I can receive the request from the browser, but I don't know how to send the data back to the browser. I don't know if I am supposed to send it back through the same port I received it from and if I need to send the browser a header etc. etc. etc.
I've looked for information on the dirt of how proxies work, but all I can find is "browser sends request to proxy, proxy send request to server blah blah blah" I need to know some real, hardcore information on how they truly work and tick.
Can anyone give me some information on how to make a proxy?
