If nobody else has figured this one out, I just did. We use a database
backed session store and I came across this after noticing extra db hits
for pages which did not use the session.
The problem is that HTTPResponse.recordSession() is referencing
transaction.session() instead of transaction._session when checking for
the existence of (and therefore need to save/send cookie for) the
Session. The session() method creates the session if it did not exist,
which defeats the purposes of what recordSession() is trying to do, and
ends up creating a Session object for every request.
The bugfix patch against Webware 0.9.4 or 0.9.3 is very simple. I'll
submit this to sourceforge shortly:
$ diff HTTPResponse.original.py HTTPResponse.py
348c348
< sess = trans.session()
---
> sess = trans._session
