https://github.com/warmcat/libwebsockets/issues/1423 If you vhost->options has the flag LWS_SERVER_OPTION_VHOST_UPG_STRICT_HOST_CHECK, then if the server is sent an upgrade request, the content of the Host: header is required to match the vhost name + port. The port is set to the well-known values of 80 and 443 if no :port on the host: value, depending on tls or not on the connection. minimal-ws-server can now take a -h flag to set this. lejp-conf (eg, lwsws) can now take a flag strict-host-check on the vhost to enable it as well.
