How to exclude cart from FastCGI caching?

Hi @icyb3r

I understand you are using the Nginx Helper plugin and that when you purge cache manually it works normally just once.

1. Can you please check if the solutions provided in this article work for you?
https://easyengine.io/wordpress-nginx/tutorials/plugins/woocommerce/

2. There may also be some server side caching involved and you’d want to check if cookies are being set by the server. This thread provides some solutions to handle that: https://serverfault.com/questions/786097/handling-caching-with-nginx-when-cookies-are-being-set-by-the-server

I hope these lead to resolution of the issue. If the problem still persists please share a copy of your site’s System Status for us to take a closer look. You can find it via WooCommerce > Status. Select “Get system report” and then “Copy for support”. Once you’ve done that, paste it here in your response.

@margaretwporg Any help?

Hi @icyb3r

Sorry for the delay – it looks like we weren’t notified of your reply.

I have tried all of the above solutions but none of them worked for me.

Thanks for sharing the System Status Report.

I see that there is a caching plugin active on your site.

### Dropin Plugins (1) ###
advanced-cache.php: advanced-cache.php

Can you please contact your host and have them temporarily disable the plugin above to see if that fixes the issue?

Keep us posted on how it goes.

Thanks

Hi, @margaretwporg

advanced-cache.php Appears to be empty.

I have no hosting company I’m the server manager and owner, and the only plugin I have is Nginx helper plugin. And yes when disabling FastCGI everything goes back to normal, but I would like to keep the FastCGI and fix the cart issue, would that be possible?

Hi @icyb3r! Thanks for writing back!

Can you share the rules you added to remove the cart page from your caching system?

Also, would you mind sharing your NGINX errors log with us, if there are any? If you have enabled it, you can find them in /var/log/nginx

I hope to hear from you soon! All the best,

Hello @chiape,

Thank you for your response, here’s what you requested.

Hi @icyb3r.

Please try replace your WooCommerce-specific rules with the following and see if that makes a difference:

if ($request_uri ~* "/(cart|checkout|my-account)/*$") {
    set $skip_cache 1;
}

Additionally, you may also want to review your permission rules for /var/log/nginx folder.

Cheers!

Hi @rynald0s,

Now it seems to be working fine thanks to you ??, but can you tell me what’s wrong with the previous rules? I mean this one:

        if ($request_uri ~* "/cart/|/services.*|/store.*|/cart.*|/account.*|/my-account.*|/checkout.*|/addons.*|/panier.*|/paiement.*|/mon-compte.*") {
            set $no_cache 1;
        }

And I’ll check the logs permissions.

Hi @icyb3r

Glad to hear. It wasn’t wrapped correctly.

Cheers!
