I'm using twisted 8.2 and (after reading glyph's latest "Twisted in 60
seconds" entry), I've realized that my sessions never expire. I never added
any session expiration code, but I thought that the default code expires
after 15 minutes.
In the below example, I modified twisted\web\server to make
Session.sessionTimeout be 30 seconds (I also put a print statement in
Session's ctor, as the log shows), then did two GETs separated by more than
30 seconds. As the log shows, it looks like the exact same session uid is
being returned. I would expect it to be deleted by Session.expire, since
time - lastModifiedTime > 30. Am I missing something?

isLeaf = True

session = request.getSession()
print session.sessionTimeout
print session.uid
print session
return "<html><body><p>Session Test</p></body></html>"
root = TestSessionResource()
reactor.listenTCP(9000, server.Site(root))
log.startLogging(sys.stdout)
reactor.run()
