I use cherrypy.request.path to find out where I've come from in my edit
pages. I then just redirect back to that location when I'm done with my
edit. This captures the paging information in the URL and puts me back
to the correct page.
At least, that's the way I recall it working. Please correct me if I'm
wrong.
