> scenarios:
> axisClient<-->synapse <--> axisServer
> 1) axisClient send request to synapse
> 2) syanpse relay request to axisServer
> 3) after axisServer received the request, break down the network between synapse and
axisServer (etc: shutdown axisServer)
> 4) axisClient doens't failure immediatly, It's alway's failure when it's timeout exceed
or synapse TimeOut handler checked time-out
> ===============================================================================================
> The more details reson I have find out is:
> When network breakdown(etc axisServer shutdown),  org.apache.synapse.transport.nhttp.ClientHandler's
corresponding callback handler is invoked (closed(), or exception(),...) . and the callback
only just shutdown the connection.
> But the sessionRequestCallback(HttpCoreNIOSender.sessionRequestCallback) registed when
establish http connection(ioreactor.connect(...)) will never be called. 
> so the failure response will not be generated and send back to axisClient.
