    I have a big problem so i hope you can help me.
    In this topic i will explain all the things so you can find where the problem is.

    I have a DEBIAN LEMP NGINX FastCGI Server and have a site in it.
    I Set it manually and fastcgi cache works without a problem but i can not use Cloudflare with this system because when i test the cache it always gives CF-Cache-Status: EXPIRED error.

    My plugins!
    I only use Autoptimize and Your Plugin WP Cloudflare Super PAge Cache
    And Enable 404 fallbacks enabld.
    I don’t use Nginx helpe i clear my cache with this command:
    rm -rf /usr/share/nginx/fastcgi_cache/*

    My nginx.conf

    user www-data;

    This is too strange that although i purge the cache from cloudflare and purge the nginx fastcgi cache with rm -rf /usr/share/nginx/fastcgi_cache/* fastcgi cache gives me to time hit one after another tests

    I don’t know where the problem is may be there is a problem at server conf
    On putty tests nginx cache works fine but cloudflare gives 2x hit information as well for the putty.
    On chrome tests nginx fastcgi tests gives 2x hit info, cloudflare gives expired error.

    This cache is not stable for me.
    Could you please help me where is the problem.

    Thanks for all

    Hi,
    Have you installed this plugin? Cause as I am checking your site I am not seeing this plugin being active on your site. If the plugin is not installed please install the plugin and set it up with your CF API key.

    Make sure there is no other plugin that has Cloudflare integration on your site and trying to manipulate CF cache beside this plugin.

    Also share a screenshot of your CF dashboard > Page Rules section.

    Hi again. Today i found something.
    I think Wp Super Cache works great but this time fastcgi cache not working.

    How i know this.

    First of all i visited a page first time
    cf-cache-status: MISS
    x-wp-cf-super-cache: cache
    x-wp-cf-super-cache-active: 1
    x-fastcgi-cache: MISS

    second test

    cf-cache-status: HIT
    x-wp-cf-super-cache: cache
    x-wp-cf-super-cache-active: 1
    x-fastcgi-cache: MISS

    WP Clouddlare super cache works
    But since adding rule cache everything, x-fastcgi-cache: always MISS WHY? I refreshed same page 3-4 times but always MISS It seems fstcgi cache not working now

    how do i get fastcgi cache to work at the same time?
    Could you please look my conf files and should i edit something there?

    Thanks

    Hi,
    as I can see the Cloudflare cache is working fine on your site: https://i.imgur.com/Wsxx3qD.png

    Now coming to why fast CGI cache is MISS while CF Cache is HIT is because when you are utilizing CF cache you mostly don’t need fastcgi or any other cache.

    So, when you purge all cache (fastcgi & CF) and then request a page as a non logghedin user. During the first request as the page HTML is not cached either is fastcgi or CF, the origin server executes all the PHP code and generate the HTML content of the page.
    Note: Till now both fastcgi & CF cache is MISS

    After that it send the output to the user. During this time (after receiving the 1st request) the CF CDN server cache that HTML page. Now when you send another request for the same page, it is intercepted by CD CDN and served from CF server without the request even hitting your origin server so your fastcgi cache didn’t get a time to update it’s system and remains MISS.

    Now if the cache gets expired in CF and the request again reaches to the origin server at this time fastcgi cache will become HIT and the cycle will continue.

    P.S: You should also check this thread: https://www.ads-software.com/support/topic/preloading-the-cache-per-edge-server/
