* DbSession stores session data in a DB table named 'YiiSession'. The table name

* it will be automatically created if {@link autoCreateSessionTable} is set true.
* DbSession uses a DB application component to perform DB operations. The ID of the DB application
* component is specified via [[connectionID]] which defaults to 'db'.
*
* The following is the table structure:
* By default, DbSession stores session data in a DB table named 'tbl_session'. This table
* must be pre-created. The table name can be changed by setting [[sessionTableName]].
* The table should have the following structure:
*
* <pre>
* CREATE TABLE YiiSession
* ~~~
* CREATE TABLE tbl_session
* (
* id CHAR(32) PRIMARY KEY,
* expire INTEGER,
* data BLOB
* )
* </pre>
* Where 'BLOB' refers to the BLOB-type of your preffered database.
* ~~~
*
* DbSession relies on {@link http://www.php.net/manual/en/ref.pdo.php PDO} to access database.
* where 'BLOB' refers to the BLOB-type of your preferred database. Below are the BLOB type
* that can be used for some popular databases:
*
* By default, it will use an SQLite3 database named 'session-YiiVersion.db' under the application runtime directory.
* You can also specify {@link connectionID} so that it makes use of a DB application component to access database.
* - MySQL: LONGBLOB
* - PostgreSQL: BYTEA
* - MSSQL: BLOB
*
* When using DbSession in a production server, we recommend you pre-create the session DB table
* and set {@link autoCreateSessionTable} to be false. This will greatly improve the performance.
* You may also create a DB index for the 'expire' column in the session table to further improve the performance.
*
* @property boolean $useCustomStorage Whether to use custom storage.
