The HTTP sniffer is just to check that you really are returning the correct reponse code and MIME type to the SE request. Don't forget that while most browsers request stuff using HTTP 1.1, that most Search Engines ask for it using HTTP 1.0, and therein might be the problem if someone botched the server configuation in some way. It is worth checking.
