• Hi, Pleskians! We are running a UX testing of our upcoming product intended for server management and monitoring.
    We would like to invite you to have a call with us and have some fun checking our prototype. The agenda is pretty simple - we bring new design and some scenarios that you need to walk through and succeed. We will be watching and taking insights for further development of the design.
    If you would like to participate, please use this link to book a meeting. We will sent the link to the clickable prototype at the meeting.
  • Our UX team believes in the in the power of direct feedback and would like to invite you to participate in interviews, tests, and surveys.
    To stay in the loop and never miss an opportunity to share your thoughts, please subscribe to our UX research program. If you were previously part of the Plesk UX research program, please re-subscribe to continue receiving our invitations.

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

Laurence@

Laurence@

Regular Pleskian
In Additional nginx directives can we do something like:


proxy_ignore_headers Cache-Control;
proxy_ignore_headers Set-Cookie;
 
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?
 
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?

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).

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.
