Hello!
There is a distinction made in the RFC between stateful and stateless
proxies. For example, stateful proxies are supposed to keep transaction
state and are responsible for re-transmission of requests.
Given that a user agent is oblivious to whether it is talking to a stateful
or stateless proxy at least some of these functions (such as re-transmission
of requests) have to be supported by the user agent anyway leading to
redundancy. ( Clearly, there are instances where proxies need to be
stateful to support certain kinds of funcitonality whereas for things such
as re-transmission, I see these as being performance enhancements in the
proxy. )
Is it required that proxies choose one mode versus the other (i.e. stateful
versus Stateless) or can they adopt an intermediate strategy?
Thanks.
Ranga.
