+/**
+ * This function is called when the {@link RequestInterceptorHandler}
encounters an object passing through it.
+ * Implementers will need to detect the type of object to determine if they
will interact with it or not. Typically,
+ * objects will be a {@code FullHttpRequest} in the case of a websocket
handshake or some form of
Review comment:
I was trying to generalize this functionality rather than pin it
particularly to `FullHttpRequest` and the initial handshake. We could say
that's not useful and that only the first HTTP request matters I guess. This
feature was largely your idea so I'll modify it to work the way you'd
envisioned.
