In ADOdb 4.91, we added a new session handler, in adodb-session2.php. It features the following improvements:
Fully supports server farms using a new database table format. The previous version used the web server time for timestamps, which can cause problems on a system with multiple web servers with possibly inconsistent times.
The new version uses the database server time instead for all timestamps.
The older database table format is obsolete. The database table must be modified to support storage of the database server time mentioned above.
Also the field named DATA has been changed to SESSDATA. In some databases, DATA is a reserved word.
The functions dataFieldName() are syncSeconds() are obsolete.
