=head1 NAME

Apache::Session::Serialize::Storable - Use Storable to zip up persistent data

=head1 SYNOPSIS

 use Apache::Session::Serialize::Storable;

 $zipped = Apache::Session::Serialize::Storable::serialize($ref);
 $ref = Apache::Session::Serialize::Storable::unserialize($zipped);

=head1 DESCRIPTION

This module fulfills the serialization interface of Apache::Session.
It serializes the data in the session object by use of Storable's
C<nfreeze()> and C<thaw()> functions.  The result is a binary object ready
for storage.
