Hmmm...
How can you see from the client's persepctive if this was a hit or miss?
I've been using the Age: header, but have been confused by this same
problem. I know I can set proxy.config.http.insert_response_via_str to 3,
but what if I don't want to expose that much information in all responses?
curl -s -D - -o /dev/null -H "Cache-Control: only-if-cached"
http://www.example.com/some/url.html
or, the Via headers, or the logs. Typically though, if you origin takes that
long that you can't distinguish between a probably cache hit, and a cache
miss, something is odd ;). Age: is never certain to specify if it's a cahce
hit or not, it's not the semantics of it at all.
