hello, I have a serious problem that I cannot identify the reason. I am logging every page access to my site to a table in my database to track some data, alonside with session, user and client data. I am seeing that same session id is given to numerous users even if their host, user-agent access times etc. are completely different. I am using session.session_id to track this data. and this session id changes every day. 1 day session_id A is given to 16000 accesses second day session_id B is given to 16000 accesses (other session ids total upto atmost 50 accesses). What can be the reason? what can be the thing that changes this session id everyday? How can I override session_id generating function (I couldnt find it) Thanks in advance, onur
