Granted the code as posted leaves the door open for the possibility for a call to request.getLocalName() to be called and cached more than once, but this would only happen very early on in the server instance's life. I had to weigh that vs. having to synchronize getting the localName from the localAddr_to_localName map every invocation... Thoughts?
