|
| 'sessionExpiration'
|
| The number of SECONDS you want the session to last.
| Setting to 0 (zero) means expire when the browser is closed.
|
| 'sessionSavePath'
|
| The location to save sessions to, driver dependent.
|
| For the 'files' driver, it's a path to a writable directory.
| WARNING: Only absolute paths are supported!

| For the 'database' driver, it's a table name.
| Please read up the manual for the format with other session drivers.

| IMPORTANT: You are REQUIRED to set a valid save path!

| Whether to match the user's IP address when reading the session data.

| WARNING: If you're using the database driver, don't forget to update
| your session table's PRIMARY KEY when changing this setting.
|
| 'sessionTimeToUpdate'
|
| How many seconds between CI regenerating the session ID.
|
| 'sessionRegenerateDestroy'
|
| Whether to destroy session data associated with the old session ID
| when auto-regenerating the session ID. When set to FALSE, the data
| will be later deleted by the garbage collector.
|
| Other session cookie settings are shared with the rest of the application,
