Hmm, got a few interesting points there. I've just tried to connect to
my webserver using plain old telnet and I got responses on both "GET
/\n" and "GET / HTTP/1.1\n\n", so I assume the error handling on my
webserver works fine and looking at the reports in the logs, so does the
logging mechanism. Thus as far as that is concerned, the webserver
itself is operating normally. The misformed HTTP/1.1 request, well... I
don't have an excuse for that other then sloppy coding while trying to
make this sockets idea work.
Actually, I've just found out what is is... A bit more experimenting
with poking around on port 80 on my local server revealed the rather
embarrasing cause: A simple missing newline. It should have been "GET
/\n" instead of just "GET /". Sloppy coding indeed. Sorry to have wasted
everyone's time, I'll go smash my head against the wall a few times.
Thank you for trying to help though! :)
