[Zope] refferencing a url from a script

Greetings again: I was wondering how you refference a url from a python script either as a redierect or as a way of POSTing data. That is to say in one instance I want the page the user is view to be redierected to some url and in the second instance I just want to POST some data something like url/post_method?TRUE=1. Thanks again -matthew
