Is there another way for Traffic Dump to know what the protocol stack is on
the server side on a per transaction basis? Without this server-side API,
it seems it would not be easy for Traffic Dump or any plugin to get this
information. It is being added to satisfy a need Traffic Dump has. As you
point out, it adds something of a symmetry that already exists as a
precedent on the client side.
Thank you for your thoughts.
