Accepted Answer

I'm assuming you've read the Wikipedia article on the HTTP protocol. If you just need more examples I'd highly recommend you download Wireshark. Wireshark is an extremely powerful packet sniffer which will allow you to watch packet communications between you and any website. In addition it will actually break down the packets and tell you a little bit about their meanings in more "human terms". It has a bit of a learning curve but it can teach you a lot about a number of different protocols including HTTP.
