And that was 50,000 requests. 3 went to the backend.

I do notice, however, that when we serve stale content we are not setting an
Age header. It seems that RFC2616[1][2] requires this for 1.1: "An HTTP/1.1
server that includes a cache MUST include an Age header field in every response
generated from its own cache." So should we setting an Age header "in every
response", even when we are serving stale cache? If so, what value do we use
for the age? The real (now expired) age? Does anyone know what real-world
affect that would have downstream?
