Hi all,
What do we mean by Dialog-Stateful Proxy? RFC 3261 introduces this term
in the paragraph for Record Route
"The URI a proxy places into a Record-Route header field is only
valid for the lifetime of any dialog created by the transaction
in which it occurs. A dialog-stateful proxy, for example, MAY
refuse to accept future requests with that value in the
Request-URI after the dialog has terminated. Non-dialog-
stateful proxies, of course, have no concept of when the dialog
has terminated, but they MAY encode enough information in the
value to compare it against the dialog identifier of future
requests and MAY reject requests not matching that information."
A Transaction Stateful Proxy maintains state associated with a single
transaction. Once the transaction is complete
it does not maintain any information about the dialog. As per the line above "A
dialog-stateful proxy, for example, MAY
refuse to accept future requests with that value in the Request-URI after the
dialog has terminated." does it mean the
Dialog-Stateful proxy maintains the past dialog information even after the
dialog is terminated?
Thanks,
Bharat
