Apache::dbi and apache::authdbi are to be used with the apache server and an embedded perl interpreter like mod_perl. they provide support for basic authentication and authorization as well as support for persistent database connections via perl's database independent interface (dbi).

o authdbi.pm provides authentication and authorization:
- optional shared cache for passwords to minimize database load
- configurable cleanup-handler deletes outdated entries from the cache
o dbi.pm provides persistent database connections:
- connections can be established during server-startup
- configurable rollback to ensure data integrity
- configurable verification of the connections to avoid time-outs.
