| 39 |  |  |  |  |  |  | Apache::Session::Serialize::UUEncode - Use Storable and C<pack()> | 
| 40 |  |  |  |  |  |  | to zip up persistent data | 
| 41 |  |  |  |  |  |  |  | 
| 42 |  |  |  |  |  |  | =head1 SYNOPSIS | 
| 43 |  |  |  |  |  |  |  | 
| 44 |  |  |  |  |  |  | use Apache::Session::Serialize::UUEncode; | 
| 45 |  |  |  |  |  |  |  | 
| 46 |  |  |  |  |  |  | $zipped = Apache::Session::Serialize::UUEncode::serialize($ref); | 
| 47 |  |  |  |  |  |  | $ref = Apache::Session::Serialize::UUEncode::unserialize($zipped); | 
| 48 |  |  |  |  |  |  |  | 
| 49 |  |  |  |  |  |  | =head1 DESCRIPTION | 
| 50 |  |  |  |  |  |  |  | 
| 51 |  |  |  |  |  |  | This module fulfills the serialization interface of Apache::Session. It | 
| 52 |  |  |  |  |  |  | serializes the data in the session object by use of Storable's C<nfreeze()> and | 
| 53 |  |  |  |  |  |  | C<thaw()> functions, and Perl's C<pack()> and C<unpack()>.  The serialized data | 
| 54 |  |  |  |  |  |  | is ASCII text, suitable for storage in backing stores that don't handle binary | 
| 55 |  |  |  |  |  |  | data gracefully, such as Postgres. |
