Analysis on HTTP request data

A while ago, a friend of mine gave me a call. Said is now in the network sales, asked if I can help him the entire automatic post machine. To tell the truth, I didn't get this piece before, I told him I tried it, can not be guaranteed. after all, is the process, self-study ability or drop. After a search, roughly grasp the automatic posting of the program roughly need to use which techniques and procedures. Here I use the httpclient framework to use the program to simulate the browser to send a request to the server. So, what requests do we need to send to the server?
