Hi,
The RFC bis-05 mentions that there are two
approaches to handling a 302 received at a client.
The first approach seems to suggest that the From,
To, Call-id, Cseq of the new request can be kept
the same with the addition of a new branch identifier
in the Via field.
Does this imply that proxies should examine
the Via branch of the previous hop to determine if
a request is a retransmission. As far as i know, a
proxy receiving such a request will note that the
From, To, Call-ID, Cseq has not changed and hence
mistake this for a retransmission from the client.
Or am i missing something ?
Thanks in advance,
Subhash Nayak
