[Zope] redirect to a renamed folder

[Tim Hicks]

Just to let people know, I solved my problem of changing a folder name and
catching old links to it.  Indirect thanks must go to Casey Duncan who
posted something to this list saying that python scripts halt traversal so
they can populate their 'traverse_subpath' binding.

I got things working by creating the script below with the old name of the
folder ('cfhl' in this case).  I knew it'd be easy in the end :-)

ps context.path() is just a python script to get me a suitable url for the
root of the site.

----
#Catches urls pointing to the old /cfhl/* folder tree
#Redirects them to the new /hlsm/* tree

import string
context.REQUEST.RESPONSE.redirect(context.path()+'/hlsm/'+string.join(traverse_subpath,
'/'))
