I had a similar issue from within an external method. I strongly
suspect that the way I solved it is not the way to do it:-)

I used
	REQUEST.redirect('next_page?back=this_page')
	return REQUEST

in next_page there is something like:
	<a href="<dtml-var back>">Back</a>

What is the proper way to do this with Zope?
