/**
 * Returns the top level domain of the server from the request. This is used to limit the Cookie
 * to the top domain instead of the full domain name.
 * <p>
 * A lot of times, individual gateways of the same domain get their own subdomain but authentication
 * shall work across all subdomains of the top level domain.
 * <p>
 * For example, when sending a request to <code>app1.domain.com</code>,
 * this returns <code>.domain.com</code>.
 *
 * @param request the HTTP request we received from the client.
 * @return the top level domain to set the cookies for.
 * Returns null if the domain is not under a public suffix (.com, .co.uk), e.g. for localhost.
