I added to the web context a session-less context as explained here
http://develop.modx.com/blog/2012/04/05/new-for-2.2.1-session-less-contexts/ but I still get a lot of entries in the session table.
I would like to disable the session writing to the db for frontend visits since I have no visitor login on my sites.
Is there anything else I need to do besides creating this context setting for "web"?
