The major change is that Squid now supports ETag and sends If-None-Match conditions in most refreshes to strengthen the cache validation and to support server side content negotiation better (Vary). Perhaps your backend server is reacting differently to requests with If-None-Match than If-Modified-Since alone. Regards Henrik
