Question Can we use "proxy_ignore_headers" in Apache & nginx Settings

[Laurence@]

In Additional nginx directives can we do something like:


proxy_ignore_headers Cache-Control;
proxy_ignore_headers Set-Cookie;

 

[Laurence@]

I tried and doesn't seem to be working. Still getting BYPASS due a cookie being set.

 

[IgorG]

I have tried to reproduce it. Added lines

proxy_ignore_headers Cache-Control;
proxy_ignore_headers Set-Cookie;

to Additional nginx directives and checked output of command:

# wget --server-response --spider http://_your_domain.tld
And really, I see there:

Set-Cookie: __cfduid=d90e80805e12314e9ecbad...

But this __cfduid is added by CloudFlare that works before target server.
Maybe it is your case?

 

[Laurence@]

The test site Herald Home - WPNEXUS is not on CloudFlare. It just sets the standard wordpress_test_cookie.

 

[Laurence@]

@IgorG - can you test on a non-CF website running WordPress? This would be a simple solution to the problem.

 

[IgorG]

Well. Default WordPress installation to default test Plesk domain. Lines

proxy_ignore_headers Cache-Control;
proxy_ignore_headers Set-Cookie;

added to Additional nginx directives.

Looks fine, isn't it?

 

[Laurence@]

Where is the "x-cache-status:" header?

Any HITs on a second run? I have the same directives and can't even get a MISS. Just a BYPASS due to the cookies. Check the headers:

Herald Home - WPNEXUS

I'm getting a cache HIT via CLI too:

But via a browser it's not hitting the cache. Is wget loading the cookies? Interestingly enough my Redis cache that hits every time in a browser is missing with wget (X-Pj-Cache-Status: miss).

[Laurence@]

Still not able to get any HIT in a browser. Always vary between cache-control: max-age=0 and cache-control: no-cache. You can test in a browser. Renders Nginx cache on WordPress useless. Help please.

 

[Laurence@]

On a default install of WordPress I'm able to get a HIT though:

Zeoliter - Fuk the Cache

Frustrating.
