## NAME
    [Apache::Session::Generate::ModUsertrack](https://www.chedong.com/phpMan.php/perldoc/Apache%3A%3ASession%3A%3AGenerate%3A%3AModUsertrack/markdown) - mod_usertrack for session ID generation

## SYNOPSIS
      use [Apache::Session::Flex](https://www.chedong.com/phpMan.php/perldoc/Apache%3A%3ASession%3A%3AFlex/markdown);

      tie %session, '[Apache::Session::Flex](https://www.chedong.com/phpMan.php/perldoc/Apache%3A%3ASession%3A%3AFlex/markdown)', $id, {
          Store     => 'MySQL',
          Lock      => 'Null',
          Generate  => 'ModUsertrack',
          Serialize => 'Storable',
          ModUsertrackCookieName => 'usertrack', # optional
      };

## DESCRIPTION
    [Apache::Session::Generate::ModUsertrack](https://www.chedong.com/phpMan.php/perldoc/Apache%3A%3ASession%3A%3AGenerate%3A%3AModUsertrack/markdown) enables you to use cookie tracked by mod_usertrack as
    session id for [Apache::Session](https://www.chedong.com/phpMan.php/perldoc/Apache%3A%3ASession/markdown) framework. This module fits well with long-term sessions, so
    better using RDBMS like MySQL for its storage.

## CONFIGURATION
    This module accepts one extra configuration option.

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

## LIMITATION WITHOUT MODPERL
    This module first tries to fetch named cookie, but will in vain 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 Apache for details.
