[OpenSER-Devel] SF.net SVN: openser: [4242] trunk

[Juha Heinanen]

  347    module keeps its internal state about endpoints that need
  348    keepalive, state that is build while messages are processed by
  349    the proxy and thus it doesn't need to transfer any information
  350    from the usrloc module, which should also improve its
  351    efficiency.

and

450 1.4.5. keepalive_state_file (string)
  451 
  452    Specifies a filename where information about the NAT endpoints
  453    and the conditions for which they are being kept alive is saved
  454    when OpenSER exits.

this may not be a good idea if entry proxy (loadbalancer) has a standby
proxy that becomes active if the other one dies, looses network
connectivity or whatever.  in that kind of situation, keeping keepalive
info in clustered database may be a better idea.
