=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>.
