=head1 NAME
Mojolicious::Sessions - Signed cookie based sessions
=head1 SYNOPSIS
use Mojolicious::Sessions;
my $sessions = Mojolicious::Sessions->new;
=head1 DESCRIPTION
L<Mojolicious::Sessions> is a very simple signed cookie based session
implementation. All data gets serialized with L<Mojo::JSON> and stored on the
client-side, but is protected from unwanted changes with a signature.
=head1 ATTRIBUTES
L<Mojolicious::Sessions> implements the following attributes.
=head2 C<cookie_domain>
my $domain = $session->cookie_domain;
$session = $session->cookie_domain('.example.com');
Domain for session cookie, not defined by default.
=head2 C<cookie_name>
my $name = $session->cookie_name;
$session = $session->cookie_name('session');
Name of the signed cookie used to store session data, defaults to
C<mojolicious>.
=head2 C<cookie_path>
my $path = $session->cookie_path;
$session = $session->cookie_path('/foo');
Path for session cookie, defaults to C</>.
=head2 C<default_expiration>
my $time = $session->default_expiration;
$session = $session->default_expiration(3600);
Time for the session to expire in seconds from now, defaults to C<3600>. The
expiration timeout gets refreshed for every request. Setting the value to C<0>
will allow sessions to persist until the browser window is closed, this can
have security implications though. For more control you can also use the
C<expires> session value to set the expiration date to a specific time in
epoch seconds.
# Expire a week from now
$c->session(expires => time + 604800);
# Expire a long long time ago
$c->session(expires => 1);
=head2 C<secure>
my $secure = $session->secure;
$session = $session->secure(1);
Set the secure flag on all session cookies, so that browsers send them only
over HTTPS connections.
=head1 METHODS
L<Mojolicious::Sessions> inherits all methods from L<Mojo::Base> and
implements the following ones.
=head2 C<load>
$session->load(Mojolicious::Controller->new);
Load session data from signed cookie.
=head2 C<store>
$session->store(Mojolicious::Controller->new);
Store session data in signed cookie.
=head1 SEE ALSO
L<Mojolicious>, L<Mojolicious::Guides>, L<http://mojolicio.us>.
