=head1 NAME

Apache::AxKit::StyleChooser::Cookie - Choose stylesheets based on a browser cookie

=head1 SYNOPSIS

    AxAddPlugin Apache::AxKit::StyleChooser::Cookie

=head1 DESCRIPTION

This module checks for the presence of a cookie named 'axkit_preferred_style' 
and sets the preferred style accordingly. 

The name of the cookie can be changed by setting the variable
C<AxStyleChooserCookieKey> in your httpd.conf:

  PerlSetVar AxStyleChooserCookieKey mystyle

Once set, this module will check for the presence of the cookie named
'mystyle' instead of the cookie named 'axkit_preferred_style'.

To use the module, simply add this module as an AxKit plugin that 
will be run before main AxKit processing is done.

  AxAddPlugin Apache::AxKit::StyleChooser::Cookie

See the B<AxStyleName> AxKit configuration directive
for more information on how to setup named style.
