__PACKAGE__
=head1 NAME
-Catalyst::Plugin::Session::State::Cookie - A session ID
+Catalyst::Plugin::Session::State::Cookie - Maintain session IDs using cookies.
=head1 SYNOPSIS
- use Catalyst qw/Session Session::State::Cookie Session::Store::Foo/;
+ use Catalyst qw/Session Session::State::Cookie Session::Store::Foo/;
=head1 DESCRIPTION
This plugin stores the session ID on the client using the cookie mechanism.
+=head1 METHODS
+
+=over 4
+
+=item make_session_cookie
+
+Returns a hash reference with the default values for new cookies.
+
+=item update_session_cookie $hash_ref
+
+Sets the cookie based on C<cookie_name> in the response object.
+
+=back
+
=head1 EXTENDED METHODS
=over 4
Will restore if an appropriate cookie is found.
-=item finalize
+=item finalize_cookies
-Will set a cookie called C<session> if it doesn't exist or if it's value is not the current session id.
+Will set a cookie called C<session> if it doesn't exist or if it's value is not
+the current session id.
+
+=item setup_session
+
+Will set the C<cookie_name> parameter to it's default value if it isn't set.
=back
=item cookie_name
-The name of the cookie to store (defaults to C<session>).
+The name of the cookie to store (defaults to C<Catalyst::Utils::apprefix($c) . '_session'>).
+
+=item cookie_domain
+
+The name of the domain to store in the cookie (defaults to current host)
+
+=item cookie_expires
+
+Number of seconds from now you want to elapse before cookie will expire.
+Set to 0 to create a session cookie, ie one which will die when the
+user's browser is shut down.
+
+=item cookie_secure
+
+If this attribute set true, the cookie will only be sent via HTTPS.
+
+=item cookie_path
+
+The path of the request url where cookie should be baked.
=back
+=head1 CAVEATS
+
+Sessions have to be created before the first write to be saved. For example:
+
+ sub action : Local {
+ my ( $self, $c ) = @_;
+ $c->res->write("foo");
+ $c->session( ... );
+ ...
+ }
+
+Will cause a session ID to not be set, because by the time a session is
+actually created the headers have already been sent to the client.
