If multiple HTTP/2 applications with the same TLS certificate are built, the
browser tries to open all of the domains using the same connection. If there is
a TLS Passthrough Load Balancer in Front, this will result in a request that is
sent to the wrong application.

To solve this, a response of `421 Misdirected Request` can be sent and the
browser will retry using a new connection.
