I am confused about the following statements though:

"DO use REQUEST.set and REQUEST.__setitem__ sparingly." "DONT stuff things that are acquisition-wrapped into REQUEST or into a session, or into any other object that is transient."

I asked about that a while ago. The answer, from Chris McDonough as I recall, is that the REQUEST object gets handled and referenced so many places inside Zope that it would probably be impossible to be sure that any property assignments you added would really get released, thus preventing garbage collection. No problem for a few REQUESTS with no added properties, but possibly a problem for code that adds and handles a lot of REQUESTS that have a lot of extra properties set. Cheers, Tom P
