Hello!
Until version 1.6.2 we had a configuration which was working fine to
force
people to hit the cache:
proxy_set_header Cookie “”;
proxy_hide_header Set-Cookie;
proxy_ignore_headers Expires Cache-Control Set-Cookie;
proxy_cache_valid 3m;
and we use a specific proxy_cache_bypass so we BYPASS the cache by
ourselves
periodically to refresh the cache (under 3m of course).
The thing is, after upgrading to 1.7, it is broken, the bypass still
works,
but there are some requests not hitting the cache.
03/Apr/2015:21:46:09 +0000 “GET / HTTP/1.1” 200 […] BYPASS ← me
refreshing the cache
[…]
03/Apr/2015:21:47:21 +0000 “GET / HTTP/1.1” 200 […] EXPIRED ← random
visitor
03/Apr/2015:21:47:29 +0000 “GET / HTTP/1.1” 200 […] EXPIRED ← random
visitor
Not only it is not hitting the first cached page, but then it should
even
hit the previous visitor cache because we use proxy_cache_use_stale
updating
Are there some new headers we need to ignore in 1.7, or any other major
change?
I’ve looked at the cache folder and i see it creating different files
with
different filenames/paths but the KEY is the same…
I had tried it with 1.7.9 and we faced the issue so we reverted back to
1.6,
i’ve just tried 1.7.11 and we still have the problem…
Thanks!
