[Zope] Zope & apache ...

Hi, I've just read the webservers.txt file and I've got a question : ). If I use apache and pcgi or cgi to pass requests to zope, rather than using the zope http server directly, do I still need to have the zope http server running? I.e. I will have apache on port 80 for example, passing requests to zope running on 8080, two servers running. Initially my plan was (is) to use mod_proxy or rewrite to just pass requests back to the zope server. Using cgi or pcgi looks like an added level of complexity at this point... Thanks Paul.
