=head1 NAME

Apache::Session::Sybase - An implementation of Apache::Session

=head1 SYNOPSIS

 use Apache::Session::Sybase;
 
 # if you want Apache::Session to open new DB handles:

 tie %hash, 'Apache::Session::Sybase', $id, {
    DataSource => 'dbi:Sybase:database=sessions;server=SYBASE',
    UserName   => $db_user,
    Password   => $db_pass,
    Commit     => 1,
 };

 # or, if your handle is already opened:

 tie %hash, 'Apache::Session::Sybase', $id, {
    Handle     => $dbh,
    Commit     => 0,    
 };

=head1 DESCRIPTION

This module is an implementation of Apache::Session.  It uses the
Sybase backing store and the Null locking scheme.  See the example,
and the documentation for Apache::Session::Store::Sybase (also for the
parameters that get passed to the backing store along with the schema
necessary to save the sessions) and Apache::Session::Lock::Null for
more details.

=head1 AUTHOR

This module was based on L<Apache::Session::MySQL> which was written
by Jeffrey William Baker <jwbaker@acm.org>; it was modified by Chris
Winters <chris@cwinters.com>.
