[Zope] Redirecting based upone user

[Simon Faulkner]

I have a list of users names in a MySQL table and I would like to write an
index_html ZPT that sends the user to show_depots?depot=user/GetUsernName
(ZPT) if they are in the MySQL list and show_countries (a different ZPT) if
they are not.

How should I go about this?  Do I make index_html a Python script or ask
them to login to a script /tracking/login maybe?
