[SR-Users] Redirect Server Including Path/Recieved Information

[Daniel-Constantin Mierla]

Hello,

I am not sure if path and received from location will be of any
information for the redirect. At least received is the proto, source and
port of incoming REGISTER. Then, the Path is to be used by location
server when forwarding requests.

Can you give more details of how path and received from location should
be used by the one receiving the 30x redirect?

Cheers,
Daniel
