Description:
HTTP/1.x and DNS demultiplexer
hddemux listens on a stream and routes incoming clients to either an HTTP/1.x backend or a DNS stream-based backend depending on the first request to appear on the stream. . This is useful when making DNS-over-TLS (RFC 7858) connections that appear to the network be HTTPS connections, for example, which makes it easier to traverse a network that would prefer to block the user from making DNS-over-TLS queries.
