"Seriously, this needs shooting in the head now. There's no reason for _anything_ to be using telnet these days, there really isn't."
But Telnet is simply a straight-up connection between two servers. It's the basis for all the other protocols including WWW (meaning I can masquerade--badly--as a WWW browser by telnetting to some server's port 80 and hand-feeding it the appropriate commands). What's really the difference between HTTPing to port 80 and Telnetting to it?
