Non-HTTP traffic can have the server-side send data outside the usual request-response pairing. (Either before a request, or extra data after a response is complete.) If so, HTTP will reject the connection as the server state is now unknown. However, if HTTP is acting as a Transparent proxy, switching to pass-through mode and disabling HTTP may be a better course of action.
Banner protocols, where the a server will respond before seeing any data will not pass through the Transparent HTTP proxy. Non-HTTP protocols that start with a pseudo-HTTP response, followed by extra data will reject the connection when the extra data is seen.
Non-HTTP data sent to the server-side not belonging to a response.
It may be possible to use HTTP::disable to disable the HTTP filter when some signature of the non-HTTP protocol is seen.
The transparent HTTP profile's passthrough-pipeline option now allows unexpected server-side ingress to switch the Transparent HTTP proxy into pass-through mode.
