Brian,
With all due respect, the code you have below is a broken attempt to handle CGI form
parsing.
Rather than retype the concerns that I've typed many times before, I'll just point you
to a few
posts I've made covering code just like this:
http://www.perlmonks.org/index.pl?node_id=77694

They shouldn't show up in QUERY_STRING. This is because you use the POST method. In
this case,
the data is sent in the body of the request issued by the user agent (browser).

STDIN doesn't read the content length. STDIN contains the data and CONTENT_LENGTH is
the length
of said data. They should match.
As a side note, I noticed that you were populating some script-specific variables in
your
form-parsing code. That's not a good idea. Each section of code should do one thing
and do it
well. It should have *no* side effects, if possible. This is called 'orthogonal'.
If code is
orthogonal, it winds up being much easier to maintain. If a section of code is
changing things
all over the place and you need to patch up that section, you may need to find all of
the other
places where that code affects things. This quickly gets to be a pain. Having
functions that
don't access any globals, but instead rely on well-defined arguments that they receive
and return
is much, much easier to maintain.
Cheers,
Curtis Poe
