John, I do not understand why you are so concern about multiple servers clashing and destroying the session data. This would be a problem if: a) Two different users got the same SID. Something that it doesn't happens, at least with Zend/PHP. This would be even a problem with only one server. b) Two different servers (or the same server) trying to access the session data for the same SID at the same time. How can a user of SM generate two accesses to session data at the same time?. And how do you use SM to generate two pararell accesses from two different webservers in the cluster? PS.- I do not use locking in my SQL session handler (only normal transactions). I have never had (or got reports from other users) about this problem, but I am interested in this discusion to find out if in theory this can happen in a webcluster running PHP. I am not convinced, ... yet ;) -- Rafael Martinez, <[EMAIL PROTECTED]> Center for Information Technology Services University of Oslo, Norway PGP Public Key: http://folk.uio.no/rafael/
