Hi @davidcamba ,
there is something strange:

It’s not exactly how it should be. It has a max-age = 0 added by some other service.

The correct value should be the one present in the header x-wp-cf-super-cache-cache-control

I see you are using Varnish. Did you configured Varnish to not cache HTML pages?

Or maybe he is adding the max_age = 0 because in the presence of the woocommerce cookie

I didn’t even know I was using Varnish…

I’m using WP Rocket and it was caching properly until I started with Cloudflare.

? Regarding to WooCommerce, I chose the options not to cache Cart and Checkout. Now I’ve disabled that options and prevented /cart and /checkout URIs to be cached.

? I also tried to active the option “Overwrite the cache-control header for WordPress’s pages using web server rules”, but it’s not working either.

Any ideas? Thank you very much.

Hi @davidcamba ,
the problem is the “max-age=0” appended to cache-control. I don’t know the service in your stack which edits this HTTP header.

I can check your htaccess if you send it to me, but I think is something at higher level such like Varnish which apparently is active (as you can see there are the x-varnish and x-cache HTTP headers into the HTTP response packet, usually set by Varnish)

In case it’s problem of Varnish, how could I solve that?

Thank you very much for your help!

Hi @davidcamba ,
Please do this test. Enable the option

Overwrite the cache-control header for WordPress’s pages using web server rules

(which must be enabled if you are using wp-rocket otherwise this interferes with Cloudflare)

and save. This option inserts rules into the htaccess file. Move all content between

# BEGIN WP Cloudflare Super Page Cache

and

# END WP Cloudflare Super Page Cache

at the top of the htaccess file.

Purge the caches (wp-rocket and cloudflare) and check the response headers of the home page.

Let me know

Hey!
I’m having the same problem, I thought I’d reply here instead of making a new thread.
I, too, get the “Cache status: EXPIRED – Please try again” error. I went ahead and checked the response headers on my homepage (incognito mode) with caching enabled, and here’s what I got:

Cache-Control: s-max-age=604800, s-maxage=604800, max-age=60
Cache-Control: max-age=0, no-cache, s-maxage=10
CF-Cache-Status: EXPIRED

Setting headers for static resources through the plugin works fine.

My server runs on Plesk, which has got a weird setup where nginx runs in front of Apache. My best guess is nginx adds it’s own cache-control headers on top of the existing ones, for whatever reason. Ideally I would just disable nginx altogether, but that’s not really possible.

My question is: I run another custom (non-wordpress) website on the same server. Will adding those overwrite lines in nginx.conf affect it in any way? Will this solve my problem if it is infact related to nginx?

Thanks!
Stelios.

Hi @steliosmac ,
sorry for the late response, I read your message only now.

Have you enabled the option to overwrite the cache-control using web server rules?

Usually on Apache you solve the problem. I also use Plesk with Nginx as frontend for Apache and so far I have not encountered any problems activating this option which forces the overwriting of cache-control with that of the plugin.

Let me know
