mod deflate from my understanding will always send the Vary header. it does it because it *might* do something to the content on subsequent requests. Whilst for you proxies are not important it doesn't mean it isn't important for everyone else - ditto using the standards :) I guess your application is an intranet one ? - hence running ie 6 with the http/1.0 ? You'll probably discover a number of other modules that will also set the Vary header - things like mod_negotiation or mod_substitute I'm sure someone will correct me if I've got this wrong.
