The process that prints out a web page form is not the same process
that gets the result of filling it out and pressing the submit
button. They don't have to have any connection and don't have to
be on the same web server. I can create a search form on my website
and submit it to google, for example.
It is sometimes convenient to do them both from one cgi and sort
out which call is being made from the params, but if you are just
getting started try making the form with a static web page and
handling only the submit in the cgi. Work up from there.
