Hi,
Via is used by the server (not the agent) to know
where to send the response of a request. The answer
MUST follow the same way than the request. it s the
record Route header which enable the agent to know
where to send the next request.
Loops are detected by Max-Forwards header and Via
Header.

Arnault
