Hi , I am quite new on varnish, so far its been really impressive doing
test and quite everything that i wanted to achieve with it,
I did some test with single server, and everything looked good, interms
of cache hit ratio and all. but now i am unable to see anything as such
as cache at all.
Could anyone please show me pointer what in my rule is causing not to cache?
( Things not working so far)
# Cache as wished: /json/showcase 1s , robot.txt 4 days, CSS/JPG/JS/ 3600s
# If everything is busted serve whatever we got for 6 h
=> vcl
