=head1 NAME
L<Data::Session::ID::Static> - A persistent session manager
=head1 Synopsis
See L<Data::Session> for details.
=head1 Description
L<Data::Session::ID::Static> allows L<Data::Session> to generate a static (constant) session id.
To use this module do this:
=over 4
=item o Specify an id generator of type Static, as Data::Session -> new(type => '... id:Static ...')
=back
=head1 Case-sensitive Options
See L<Data::Session/Case-sensitive Options> for important information.
=head1 Method: new()
Creates a new object of type L<Data::Session::ID::Static>.
C<new()> takes a hash of key/value pairs, some of which might mandatory. Further, some combinations
might be mandatory.
The keys are listed here in alphabetical order.
They are lower-case because they are (also) method names, meaning they can be called to set or get
the value at any time.
=over 4
=item o id => $string
Specifies the static (constant) id to 'generate'.
This key is normally passed in as Data::Session -> new(id => $string).
Default: 0.
This key is mandatory, and can't be 0.
=item o verbose => $integer
Print to STDERR more or less information.
Typical values are 0, 1 and 2.
This key is normally passed in as Data::Session -> new(verbose => $integer).
This key is optional.
=back
=head1 Method: generate()
Generates the next session id (which is always what was passed in to new(id => ...) ), or dies if it
can't.
Returns the new id.
=head1 Method: id_length()
Returns 32 because that's the classic value of the size of the id field in the sessions table.
This can be used to generate the SQL to create the sessions table.
=head1 Support
Log a bug on RT: L<https://rt.cpan.org/Public/Dist/Display.html?Name=Data-Session>.
