[Zope-dev] __before_publishing_traverse__ calls RESPONSE.redirect(): is there another way to change the browser URL?

[Casey Duncan]

What you are looking for sounds like "stateful" through-the-web functiona=
lity.

I think you should use sessions to remember the form fields and/or whethe=
r the=20
user has been to this URL before.

I am suspect of an app design that makes a single URL mean different thin=
gs in=20
this way, however. I suspect there is a much easier way to accomplish wha=
t=20
you want that does not use traversal hooks or magic redirect descriminati=
on.

I'm still not sure I'm seeing the big picture of what you are really tryi=
ng to=20
accomplish here.
