The trailing slash is actually very important. If your browser isn't
told that it must be there then all your relative page references can
be screwed up. Thus, you don't really have a choice but to ensure it
is there.

That said, I would highly discourage you from using a directory as a
target of a form post. Instead be explicit and use /pyweb/index.py
instead as target of form.

Any particular reason why you wouldn't want to do that?
