=head1 NAME

Apache::Session::Generate::ModUsertrack - mod_usertrack for session ID generation

=head1 SYNOPSIS

use Apache::Session::Flex;

tie %session, 'Apache::Session::Flex', $id, {
      Store     => 'MySQL',
      Lock      => 'Null',
      Generate  => 'ModUsertrack',
      Serialize => 'Storable',
      ModUsertrackCookieName => 'usertrack', # optional
  };

=head1 DESCRIPTION

Apache::Session::Generate::ModUsertrack enables you to use cookie
tracked by mod_usertrack as session id for Apache::Session
framework. This module fits well with long-term sessions, so better
using RDBMS like MySQL for its storage.

=head1 CONFIGURATION

This module accepts one extra configuration option.

=over 4

=item ModUsertrackCookieName

Specifies cookie name used in mod_usertrack. C<Apache> for default, so
change this if you change it via C<CookieName> directive in
mod_usertrack.

=back

=head1 LIMITATION WITHOUT MOD_PERL

This module first tries to fetch named cookie, but will in vain B<ONLY
WHEN> the HTTP request is the first one from specific client to the
mod_usertrack enabled Apache web server. It is because if the request
is for the first time, cookies are not yet baked on clients.

If you run scripts under mod_perl, this module tries to steal (not yet
baked) cookie from Apache request notes.

See L<Apache> for details.
