[Zope] simple question (I hope)

[Sam Gendler]

I have a folder that I want to move to a new location, but I want old
bookmarks to still work.  I wanted to stick a RESPONSE.redirect call in
the standard_html_error in the old folder (that has no content in it),
that redirects to the same object as the one requested with a new path. 
Does anyone have any idea how I might go about constructing the
redirection url from the standard_html_error method?
