i have been using a mysql database custom session handler (not using cookies) and was having problems getting the session data to be saved consistantly on my database driven website
clients also have to navigate across domains for website management at times so i have some special code to make all this happen relatively seamlessly and to ensure that each person's data is secure.
i added session_write_close() at the very end of the last script that set session data and solved the problem.
i am not sure why, but it seems the calls to write and close were not always being made (i was not smart enough to figure it out)
now that the session_write_close() call is being made, my problems seemed to have disappeared - hopefully for good.
hope this helps someone.
