Added an origin check to web sockets to prevent cross-site hijacking attacks on
users using older or niche browser that do not support SameSite cookies and
attacks across sub-domains that share the same root domain.
The check requires the host header to be set so if you use a reverse proxy
ensure it forwards that information otherwise web sockets will be blocked.
