From: Fredrik Thulin <[EMAIL PROTECTED]> How is deactivating subscriptions as per RFC3265 supposed to actually be possible?
When the UACs send their new SUBSCRIBEs, how would it get to "the other node in the server cluster"? There seem to be two possibilities -- One is that one domain name has multiple addresses, the addresses of the set of nodes. In that case, once a node has decided to go off-line, it should not respond to requests that it receives, and not accept new TCP connections. So any agent that attempts to send a request to a node going off-line will see the request time-out, and the agent will eventually retry with another address for the same domain name. A better method is to have some sort of forking proxy (either in a proxy or the UAC), whereby the To address of the SUBSCRIBE sent by the UAC is forked to the multiple nodes. Then a node that is going off-line can respond to all new requests with 503 (Service Unavailable), and the forking proxy will try the other nodes.
