Session File Storage
To store one file per session on file system, use
\Koldy\Session\Adapter\File class. Options array accepts only
session_save_path which should be the full path to the folder where session files should be written. If this is not
/storage/session folder will be used. Final config example should look like this:
return [ 'adapter_class' => '\Koldy\Session\Driver\File', 'options' => [ 'session_save_path' => '/var/tmp/session' ], 'cookie_life' => 0, 'cookie_path' => '/', 'cookie_domain' => '', 'cookie_secure' => false, 'session_name' => 'koldy', 'http_only' => true, 'sid_length' => 32, 'sid_bits_per_character' => 4 ];
If folder you set doesn't exists, framework will try to create it while trying to write session file. If it fails to
create the folder,
\Koldy\Filesystem\Exception will be thrown.
CAUTION! If you have high traffic site, then using file storage won't be good idea because PHP will constantly try to read and write on filesystem. Instead of file driver, consider using database or some other session adapter.
Are you behind load balancer? File session storage can work on cloud only if you have load balancer that will persist session on incoming requests. This means that all requests for end user has to be routed to the same web node.
