SETTINGS persistence

[mnot]

From the SPDY draft:

""A SETTINGS frame [...]. When the server is the sender, the sender can request that configuration data be persisted by the client across SPDY sessions and returned to the server in future communications.""

The concern here is that this provides another mechanism by which servers are able to track clients.

Discussed at SF Interim; general feeling is that settings persisitence is not the best way to achieve the goal (DoS mitigation). James to propose a new "reconnect with last settings" GOAWAY flag; Gabriel to look into ALPN settings communication (as well as Upgrade).

... however, it WOULD be required for CWND setting (if we choose to re-add it).

Remove settings persistence.
