Yes, you should have mentioned that SimpleHttp was not the one-liner you
were looking for. That would have been useful to know :)
Your request was for a one-liner web server, and you claimed to have
done a search which came up with nothing relevant. Since a simple search
did in fact come up with an apparently relevant one-liner, the most
obvious conclusions were that your search skills are very lousy, or that
you were mistaken (i.e. lying) about having attempted to search first.
Coming from an apparent first-time poster with no reputation I was aware
of, neither would have surprised me. I'm glad that neither is actually

That would have been useful information to have mentioned at the time.
For what little it's worth, here's a 15 line socket-based web server:
template = ('HTTP/1.0 200 OK\n\n<html><head><title>Welcome %s!</title>'
'</head><body><h1>Header...</h1>...and body.<br>Your request was: '
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
print "Listening on port 8080"
client, address = sock.accept()
cfile = client.makefile('rw', 0)
cfile.write(template % (str(address), cfile.readline().strip()))
Save this as "web.py", run "python web.py", and then in your browser go
Turning this into a one-liner is left as an exercise. This may be useful:
