I need to write a feed parser that takes a url for any Atom or RSS feed and transform it into an Atom feed. I done the transformation part but I want to support conditional HTTP requests. I have not been able to find any examples that show:
1. How to read the Last_Modified or ETag header value from the requester 2. How to set the corresponding HTTP header value, either a 302 not modified or the new Last_Modified date and/or ETag values -- http://mail.python.org/mailman/listinfo/python-list
