[squid-users] 2.7.9 to 3.5 CentOS No-Cache

[Tory M Blue]

Greetings all, been a bit.

So I'm working on a new server config and loaded the latest 3.5 and have
tweaked my 2.7 configs a bit. Things are working but I've got one that I
can't figure out.

I have a test that insures that objects with an explicit "
Cache-Control: no-cache" header are NOT cached by Squid. This is done by
keeping a special hit counter on the server and counting origin requests. A
unique URL is fetched exactly 10 times, and all of them are asserted to be
cache misses (both Squid headers must be MISS). At the end, the hit counter
is tested and made sure it equals the number of requests (10)."

I'm getting a fail when testing against 3.5, meaning it's providing a cache
object

Miss with no-cache                  | FAIL    <------

w/ 2.7.9 config
Miss with no-cache                  | Pass

X-Cache: MISS from dev-cache
X-Cache-Lookup: MISS from dev-cache:80

*I get 10 of the above responses (test passes).*

I'm wondering what I'm missing, 3.5 should be fully http 1.1 compliant
meaning that there should not be any squid directives guiding this (nor can
I find any). If the client sends a "Cache-Control: no-cache" it should be
honored natively ya?

Thanks for any pointers

Tory
