They will eventually get cleaned up by PHP if you are using the session_save_path as specified in php.ini. There are settings in php.ini that control how often this happens: a.. session.gc_probability specifies the probability that the gc (garbage collection) routine is started on each request in percent. Defaults to 1. a.. session.gc_maxlifetime specifies the number of seconds after which data will be seen as 'garbage' and cleaned up. Note: If you are using the default file-based session handler, your filesystem must keep track of access times (atime). Windows FAT does not so you will have to come up with another way to handle garbage collecting your session if you are stuck with a FAT filesystem or any other fs where atime tracking is not available. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
