Configuring caching plugins

Oftentimes if using caching plugins they’ll already exclude these pages. Otherwise make sure you exclude the following pages from the cache through your caching systems respective settings.

• Cart
• My Account
• Checkout

These pages need to stay dynamic since they display information specific to the current customer and their cart

If the caching system you’re using offers database caching, it might be helpful to exclude _wc_session_ from being cached. This will be dependent on the plugin or host caching so refer to the specific instructions or docs for that system.

Cookies in WooCommerce help track the products in your customers cart, can keep their cart in the database if they leave the site, and powers the recently viewed widget. Below is a list of the cookies WooCommerce uses for this, which you can exclude from caching.

Ensure you add ‘mfunc’ to the ‘Ignored comment stems’ option in the Minify settings.

WooCommerce is fully compatible with WP-Rocket. Please ensure that the following pages (Cart, Checkout, My Account) are not to be cached in the plugin’s settings.

WooCommerce is natively compatible with WP Super Cache. WooCommerce sends information to WP Super Cache so that it doesn’t cache the Cart, Checkout, or My Account pages by default.

if (req.url ~ "^/(cart|my-account|checkout|addons)") {
 return (pass);
 }
if ( req.url ~ "\?add-to-cart=" ) {
 return (pass);
 }

Check out the following WordPress.org Support forum post on how cookies may be affecting your varnish coding.

Add this to vcl_recv above "if (req.http.cookie) {":

# Unset Cookies except for WordPress admin and WooCommerce pages 
if (!(req.url ~ "(wp-login|wp-admin|cart|my-account/*|wc-api*|checkout|addons|logout|lost-password|product/*)")) { 
unset req.http.cookie; 
} 
# Pass through the WooCommerce dynamic pages 
if (req.url ~ "^/(cart|my-account/*|checkout|wc-api/*|addons|logout|lost-password|product/*)") { 
return (pass); 
} 
# Pass through the WooCommerce add to cart 
if (req.url ~ "\?add-to-cart=" ) { 
return (pass); 
} 
# Pass through the WooCommerce API
if (req.url ~ "\?wc-api=" ) { 
return (pass); 
} 
# Block access to php admin pages via website 
if (req.url ~ "^/phpmyadmin/.*$" || req.url ~ "^/phppgadmin/.*$" || req.url ~ "^/server-status.*$") { 
error 403 "For security reasons, this URL is only accesible using localhost (127.0.0.1) as the hostname"; 
} 
#

Add this to vcl_fetch:

# Unset Cookies except for WordPress admin and WooCommerce pages 
if ( (!(req.url ~ "(wp-(login|admin)|login|cart|my-account/*|wc-api*|checkout|addons|logout|lost-password|product/*)")) || (req.request == "GET") ) { 
unset beresp.http.set-cookie; 
} 
#

This is due to the My Account page being cached, Some hosts with server-side caching don’t prevent my-account.php from being cached.

If you’re unable to reset your password and keep being returned to the login screen, please speak to your host to make sure this page is being excluded from their caching.
