Yes (but see below).

There are 2 cases:

1. The request is RMPP'd (SA GetMulti is an example of this). The
responder can redirect in the middle of the request. This is the more
straightforward one.

2. I think you (and Roland) are talking about when a SA
GetTable/GetTraceTable request is made which is not RMPP'd but elicits a
RMPP response. How this is done is an "implementation issue". I think
there are 2 valid choices: (1) complete the transaction and redirect the
next request, or (2) terminate the transaction (cause the request to be
retried) and redirect that request to the new location.
