note 102685 added to book.session

Please note, that database is NOT recommended for session storage. It can be a big performance bottleneck, especially in replicated environments. For saving sessions, file handler seems to be very effective for most setups, except those situations: - if performance is an issue, the directory which stores session files can be mounted as tmpfs (ram disk). - if sharing sessions across multiple webservers is needed (in clustered environments), use memcache for storing session information (tip: you can setup more than one instance of memcache eliminate single point of failure). This method, however, sets a limitation of session size to 64k (this should be enough for most applications) - don't use NFS for sharing session files between webservers, it does not handle locking correctly and can cause corruption of session data. ---- Server IP: 69.147.83.197 Probable Submitter: 89.204.137.89 ---- Manual Page -- http://www.php.net/manual/en/book.session.php Edit -- https://master.php.net/note/edit/102685 Del: integrated -- https://master.php.net/note/delete/102685/integrated Del: useless -- https://master.php.net/note/delete/102685/useless Del: bad code -- https://master.php.net/note/delete/102685/bad+code Del: spam -- https://master.php.net/note/delete/102685/spam Del: non-english -- https://master.php.net/note/delete/102685/non-english Del: in docs -- https://master.php.net/note/delete/102685/in+docs Del: other reasons-- https://master.php.net/note/delete/102685 Reject -- https://master.php.net/note/reject/102685 Search -- https://master.php.net/manage/user-notes.php
