vBulletin caching proxy


I’m trying to build similar configuration to this one
but using nginx. Aparently there is no problem caching static files and
php generated css, but websites itselves dont cache.

Here is part config of proxy:

        proxy_pass http://ip:78;
        proxy_cache one;
        proxy_cache_key $host$request_uri;
        proxy_cache_valid 5m;
        proxy_cache_methods GET HEAD;
        proxy_no_cache $cookie_bb_imloggedin $cookie_bb_password
$cookie_bb_userid $nocache;
        proxy_ignore_headers  X-Accel-Expires Expires Cache-Control;

This goes to cache:
This doesn’t:

I’m aware of Pragma: private and Cache-control: private, I commented it
out from code with no results. Also Cache-control should be ignored. Anu

I figured out that it must be something with headers. Does anybody knows
why nginx ignores cache with those headers?

Cache-control should be ignored according to proxy cache settings…

Since 0.8.44 nginx doesn’t cache by default responses with
Set-Cookie. If you want them to be cached you have to add
“proxy_ignore_headers Set-Cookie”.

Note well: you may also want to add “proxy_hide_header Set-Cookie”
(or make sure cookies set aren’t private, or make sure your
proxy_cache_key distinct for different users).

Thanks that works good. It’s by design guest cache controlled by cookie
‘imloggedin’=1 So even if cookies are set it’s ok to be public.

I was relying on wiki since there is no english documentation. Could you
please make english docs as much up to date as russian?
