NAME

Catalyst::Plugin::Session::State::Cookie - Maintain session IDs using cookies.

SYNOPSIS

    use Catalyst qw/Session Session::State::Cookie Session::Store::Foo/;

DESCRIPTION

In order for Catalyst::Plugin::Session to work the session ID needs to be stored on the client, and the session data needs to be stored on the server.

This plugin stores the session ID on the client using the cookie mechanism.

METHODS

Returns a hash reference with the default values for new cookies.

Sets the cookie based on cookie_name in the response object.

calc_expiry
delete_session_id
extend_session_id
get_session_id
set_session_id

EXTENDED METHODS

prepare_cookies

Will restore if an appropriate cookie is found.

finalize_cookies

Will set a cookie called session if it doesn't exist or if its value is not the current session id.

setup_session

Will set the cookie_name parameter to its default value if it isn't set.

CONFIGURATION

The name of the cookie to store (defaults to Catalyst::Utils::apprefix($c) . '_session').

The name of the domain to store in the cookie (defaults to current host)

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.

If this attribute set to 0 the cookie will not have the secure flag.

If this attribute set to 1 (or true for backward compatibility) - the cookie sent by the server to the client will get the secure flag that tells the browser to send this cookie back to the server only via HTTPS.

If this attribute set to 2 then the cookie will get the secure flag only if the request that caused cookie generation was sent over https (this option is not good if you are mixing https and http in your application).

Default value is 0.

If this attribute set to 0, the cookie will not have HTTPOnly flag.

If this attribute set to 1, the cookie will got HTTPOnly flag that should prevent client side Javascript accessing the cookie value - this makes some sort of session hijacking attacks significantly harder. Unfortunately not all browsers support this flag (MSIE 6 SP1+, Firefox 3.0.0.6+, Opera 9.5+); if a browser is not aware of HTTPOnly the flag will be ignored.

Default value is 1.

Note1: Many people are confused by the name "HTTPOnly" - it does not mean that this cookie works only over HTTP and not over HTTPS.

Note2: This parameter requires Catalyst::Runtime 5.80005 otherwise is skipped.

This attribute configures the value of the SameSite flag.

If set to None, the cookie will be sent when making cross origin requests, including following links from other origins. This requires the "cookie_secure" flag to be set.

If set to Lax, the cookie will not be included when embedded in or fetched from other origins, but will be included when following cross origin links.

If set to Strict, the cookie will not be included for any cross origin requests, including links from different origins.

Default value is Lax. This is the default modern browsers use.

Note: This parameter requires Catalyst::Runtime 5.90125 otherwise is skipped.

The path of the request url where cookie should be baked.

For example, you could stick this in MyApp.pm:

    __PACKAGE__->config( 'Plugin::Session' => {
        cookie_domain  => '.mydomain.com',
    });

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.
