Subject Re: Forwarding bridge - connect at need feature ?
Date Wed, 26 May 2010 09:06:49 GMT
that is an interesting use case. A combination of the failover: transport
that only reconnects on demand and an inactivity timeout that does not use
keepAlives could do it. When there is no activity, the connection can
timeout, that is possible on trunk with the useKeepAlive=false attribute,
having the failover transport only reconnect on demand may need some code
changes as it typically tries to reconnect after some timeout. You could
make that reconnect delay very large I guess.
