| 55 |  |  |  |  |  |  |  | 
| 56 |  |  |  |  |  |  | Apache::Session::Lock::Null fulfills the locking interface of | 
| 57 |  |  |  |  |  |  | Apache::Session, without actually doing any work.  This is the module to use | 
| 58 |  |  |  |  |  |  | if you want maximum performance and don't actually need locking. |
