Works for now. However, if new translators are introduced that actually 
perform chaining on the server side, this method will not be good 
enough. For e.g., a translator chain like this is possible

Server1                              Server2

  protocol/client  ------------------ protocol/server

Work in progress translators like NSR[1] will possibly use such a scheme.
