Interceptor: How to verify the current context (inbound/outbound and request/response)

[Wulff, Oliver]

Hi there

I can check whether handleMessage is called in the context of inbound or 
outbound with the following lines:

boolean isOutbound = message == message.getExchange().getOutMessage()
               || message == message.getExchange().getOutFaultMessage();

But how can I check whether it's outbound in the context before the request is 
sent or a response is sent?

Thanks
Oliver
