Chapter: jSession: allowing to choose the storage : files, database
|« jWiki: generating contents from wiki contents||^ Class utilities|
jSession provides alternative storage engines. Configuration is done in app/var/config/defaultconfig.ini.php :
Session name ¶
You may need to change the session's name (default is PHPSESSID).
To make such a change, you can use the following configuration directive :
[sessions] name = "mysession"
NB : only alpha-numeric chars are allowed.
File storage ¶
Storing session files in default path may not be a good idea, as that path is often worldwide readable/writable, like /tmp/ for example.
To make jSession store sessions in your own defined path :
[sessions] storage = "files" files_path = "app:var/sessions/"
NB : app: and lib: keywords are converted.
Database storage ¶
You may need to store your sessions in data, for example when you are doing load-balancing with multiple front servers.
jSession uses jDao :
[sessions] storage = "dao" dao_selector = "jelix~jsession" dao_db_profile = ""
NB : a default dao is provided in the jelix module. The selector is jelix~jsession.
The corresponding DB creation request :
CREATE TABLE `sessions` ( `id` varchar(64) NOT NULL, `creation` datetime NOT NULL, `access` datetime NOT NULL, `data` text NOT NULL, PRIMARY KEY (`id`) ) DEFAULT CHARSET=utf8;
