If you really want to do it in parallel instead, you'll probably need
to have your tcp backend tag responses using some id that is unique to
each connection so that each http request knows if specific incoming
data is meant for it or another http request. Additionally, you might
consider writing a class or function that wraps the tcp stream and
emits events containing whole incoming messages, to make things a
little easier. This would allow you to do something like:
// inside http request handler
streamWrapper.write('foo');
streamWrapper.once(someUniqueId, .....);
// or use .on() if you expect more than one message, but remember to
remove the event handler later on so as to prevent leaking
// inside streamWrapper somewhere after forming a complete incoming
message
streamWrapper.emit(uniqueIdFromData, ....);
