Both good ideas; I strongly recommend anybody playing with
servlets to get the HTTP spec (or maybe Clint Wong's _Programming Web
Clients_, from O'Reilly, even if it does use Perl for the example code
:-), sit down and play with the server at a telnet prompt. Actually I
tend to use emacs, shell out and run telnet from there, so I can use
the buffer editing commands.
Another thing I strongly recommend is getting and installing some
simple proxy server on your machine, and using it to watch your
browser and server talk to each other. If you're using Linux you have
a lot of fine alternatives, but for a windows box, I found a program
called HttpProxySpy to be quite handy, last year. It was designed
specifically to make it easy to watch the action, so it displayed each
message as a single line and expanded it to show the whole message
when you clicked on it. It completely changes the experience of doing
web coding. Without a proxy to watch, it's like picking a lock, going
by "feel" alone, a painstaking process.
