Catalyst::Plugin::Session::State::Cookie(3) 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

make_session_cookie
Returns a hash reference with the default values for new cookies.
update_session_cookie $hash_ref
Sets the cookie based on "cookie_name" in the response object.
calc_expiry
calculate_session_cookie_expires
cookie_is_rejecting
delete_session_id
extend_session_id
get_session_cookie
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

cookie_name
The name of the cookie to store (defaults to "Catalyst::Utils::apprefix($c) . '_session'").
cookie_domain
The name of the domain to store in the cookie (defaults to current host)
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.
cookie_secure
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 send by the server to the client will got the secure flag that tells the browser to send this cookies back to the server only via HTTPS.

If this attribute set to 2 then the cookie will got 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 you application).

Default vaule is 0.

cookie_httponly
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 peole 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.

cookie_path
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.
