Which indicates that the public key is being updated by vary headers
which looks a bit odd..
what is this??
accept-encoding="gzip,%20deflate"
Thanks,

The above picture should be valid for a very long time.
but still it wont be "cached" by squid.
it shows a tcp_miss but with 304 in some cases.
let see the headers:

Which should be cachable for at-least very very long time on all caches.
the local browser indeed caches this response but squid that I am using
is not caching.
I am trying to debug it and findout if the reason is ETAG, VARY or any
other logical reason.
in storelog I get:

Which I am unsure on how to read now.
in squid access.log I see that:
1372835884.106 127 192.168.10.124 TCP_MISS/200 42410 GET
http://image.slidesharecdn.com/rhintrotoglusterfsoct11final-111028123627-phpapp01/95/slide-1-728.jpg

- HIER_DIRECT/88.221.156.163 image/jpeg
there is no revalidation which is preferred and should be done in a case
of reload using refresh_patttern
I also tried another thing:
1372835980.822 155 192.168.10.124 TCP_MISS/200 42410 GET
http://image.slidesharecdn.com/rhintrotoglusterfsoct11final-111028123627-phpapp01/95/slide-1-728.jpg?1319823415

- HIER_DIRECT/88.221.156.163 image/jpeg
Which uses StoreID and it seems like the internals of StoreID do the
trick for most sites but in this case there is another issue which I am
unable to identify myself yet.
Any points to findout what is going on and why squid wouldn't cache a
response that firefox explorer and chrome would do???
Thanks,
Eliezer
