cgif.py defines class cigForwarder, a sub-class of cgi.FieldStorage,
designed to facilitate the implementation of simple proxies
for massaging input data to a site (such as an input form)
and parsing the output prior to sending it to the caller.
It will pass any form data from the caller to the target url unchanged
unless you do something with it before calling the post() method.
