=head1 NAME
Plack::Session::Store::Cache - Cache session store
=head1 SYNOPSIS
use Plack::Builder;
use Plack::Session::Store::Cache;
use CHI;
my $app = sub {
return [ 200, [ 'Content-Type' => 'text/plain' ], [ 'Hello Foo' ] ];
};
builder {
enable 'Session',
store => Plack::Session::Store::Cache->new(
cache => CHI->new(driver => 'FastMmap')
);
$app;
};
=head1 DESCRIPTION
This will persist session data using any module which implements the
L<Cache> interface. This offers a lot of flexibility due to the many
excellent L<Cache>, L<Cache::Cache> and L<CHI> drivers available.
This is a subclass of L<Plack::Session::Store> and implements
its full interface.
=head1 METHODS
=over 4
=item B<new ( %params )>
The constructor expects the I<cache> param to be an object instance
which has the I<get>, I<set>, and I<remove> methods, it will throw an
exception if that is not the case.
=item B<cache>
A simple accessor for the cache handle.

=head1 BUGS

exception. If you find a bug please either email me, or add the bug
to cpan-RT.
