Hi > Can someone explain why the object is not being returned as a cached object?
Because your client is performing a conditional request and so revalidating using If-None-Match/Etag headers the already cached object in your machine. Your client is issuing: > 15 RxHeader c If-None-Match: "4ee85970d12afd8992d3dc1651f07b9d" It means: please send me the object if none match with this Etag value. Varnish responds: > 15 TxStatus c 304 > 15 TxResponse c Not Modified [...] > 15 TxHeader c ETag: "4ee85970d12afd8992d3dc1651f07b9d" It means: the object you have is the same one I have. Transfering an object you already have is a waste of resources :) regards Lucas Brasilino > I'm confused around the fact that it says there is a 'hit', but the > X-Varnish header only has 1 field. > I read that if the Set-Cookie header is sent, then varnish does not cache > the object, but I'm pretty sure thats not being sent.
