=head1 NAME

Jifty::Web::Session::None - A null session handler for jifty

=head1 DESCRIPTION

Jifty depends on its sessions to keep users logged in, to store
continuations and to allow developers to store user-specific data.
In general, you don't want to disable them. But sometimes, the
development benefits of Jifty lead you to build applications that
genuinely don't want per-user sessions. That's where 
C<Jifty::Web::Session::None> comes in. By specifying that you want
to use C<Jifty::Web::Session::None> as your Jifty session handler, 
you tell Jifty to avoid ever reading, writing or storing a user session.
No cookies get set. Nothing gets stored in the database.

=head1 USAGE

   Web:
