Mojo::Cookie::Response - HTTP response cookie

=head1 SYNOPSIS

  use Mojo::Cookie::Response;

  my $cookie = Mojo::Cookie::Response->new;
  $cookie->name('foo');

  say "$cookie";

=head1 DESCRIPTION

L is a container for HTTP response cookies, based on L

=head2 expires

  my $expires = $cookie->expires;
  $cookie     = $cookie->expires(time + 60);

Expiration for cookie.

=head2 host_only

  my $bool = $cookie->host_only;
  $cookie  = $cookie->host_only($bool);

Host-only flag, indicating that the canonicalized request-host is identical to the cookie's L.

=head2 httponly

  my $bool = $cookie->httponly;
  $cookie  = $cookie->httponly($bool);

HttpOnly flag, which can prevent client-side scripts from accessing this cookie.

=head2 max_age

  my $max_age = $cookie->max_age;
  $cookie     = $cookie->max_age(60);

=head2 path

  my $path = $cookie->path;
  $cookie  = $cookie->path('/test');

=head2 samesite

  my $samesite = $cookie->samesite;
  $cookie      = $cookie->samesite('Lax');

SameSite value.

=head2 secure

  my $bool = $cookie->secure;
  $cookie  = $cookie->secure($bool);

Secure flag, which instructs browsers to only send this cookie over HTTPS connections.

=head1 METHODS

L inherits all methods from L and implements the following new ones.

=head2 parse
