-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Sandy,
I am about to go live with my campus' implimentation, and our setup is much the same as yours is described. 1. We use the webflow method. It's what worked for us. 2. We were having some serious database side issues and proformance problems *until* we indexed the foreign keys in the database on (I believe) the ticket registry table, and all the problems disappeared. We have run the same tests (with Canoo and Selenium) against our cas install, and we went from 80%+ of simply login/logout/repeat transactions failing, to 0% 3. I would like this answer as well.
