Misdirected Request Plug

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.

Installation

The package can be installed by adding plug_misdirected_request to your list of dependencies in mix.exs:

def deps do

  ]
end
