Description

This lightweight plugin prevents NGINX caching for WooCommerce pages to ensure stock levels, cart contents, and checkout functionality remain accurate.

Many NGINX caching setups can accidentally serve cached product, cart, or checkout pages, which may cause issues such as:

Showing incorrect stock availability
Displaying outdated cart totals
Serving stale pricing or product information

This plugin ensures that all WooCommerce product, cart, checkout, and account pages bypass server caching, while still allowing other pages to remain cached for performance.

Note that this plugin does not handle updates so for security, you may need to update this yourself.

Features

Bypasses NGINX caching for:
- Product pages
- Cart page
- Checkout page
- My Account pages
Super-lightweight and efficient
Compatible with most NGINX caching setups
No configuration required — just install and activate

Installation

Upload the plugin folder to your /wp-content/plugins/ directory, or install via GitHub.
Activate the plugin through the Plugins menu in WordPress.
No further configuration is required.

Notes

This plugin does not disable caching for other pages (e.g., homepage, blog posts, category pages) — they remain cached for improved performance.
Designed to work with NGINX caching setups that respect the DONOTCACHEPAGE constant.
