Okay, so there is no proxy server from your post.
What is the result of simple telnet GET requests to port 80?
Can you maintain a connection with an HTTP/1.1 request using this method?
Do you have an example of the fetch program in question?
Aside from "guessing" server responses to speed things up, lynx runs a fairly
straightforward network socket connection to port 80 AFAIK.
