## Description

Cache Master is an extremely lightweight, high-performance cache plugin that speeds
up your WordPress sites on the fly. The core of Cache Master is driven by Shieldon
Simple Cache, a PSR-16 simple cache library.

Open sourced on GitHub:

 * [terrylinooo/simple-cache](https://github.com/terrylinooo/simple-cache) (Simple
   Cache library)
 * [terrylinooo/cache-master](https://github.com/terrylinooo/cache-master) (Cache
   Master plugin)

First release date: October, 1, 2020

### Features

 * Extremely lightweight and high-performance.
 * Support up to 10 cache drivers such as File, Redis, Memcache, Memcached, APC,
   APCu, WinCache, MySQL, SQLite, and MongoDB.
 * Provide detailed cache statistics, easy to manage.
 * Compatible with the WooCommerce plugin.
 * And more…

Notice:

Before you install and use this plugin, please read the following notices carefully:

 * Logged-in users will not trigger the caching process.
 * A debug message will be appended to the end of the page’s source code: `<!-- 
   This page is cached by the Cache Master plugin. //-->`. This is intended for 
   debugging purposes only, confirming that the page is being cached. This message
   can be disabled in the Settings page.

If you encounter issues with your website when using Cache Master, please report
the problem on GitHub and list all plugins installed on your website. I’ll investigate
the problem and provide a fix.

## Installation

 * Activate the plugin via the ‘Plugins’ screen in WordPress.
 * Navigate to the Cache Master menu in the Plugins section and configure your options.

## FAQ

### Should I disable other cache plugins?

Cache Master caches entire webpages into static HTML files. Therefore, it is recommended
to disable other similar cache plugins that perform the same function. However, 
it can function alongside object cache plugins without issue.

### How can I determine whether the caching is working or not?

Be aware that logged-in users will not trigger the caching process. To verify caching,
use incognito mode or a different browser to revisit the same webpage, and then 
you can check the cache status in one of the following ways:

 * View the source code of the webpage and check the debug message as shown in screenshot(
   L).
 * Enable the benchmark information in the footer section as shown in screenshot(
   K), where you can see the cache status.

If there is no debug message in the source code, or if the cache status consistently
displays ‘No’, there might be a plugin conflict with Cache Master that prevents 
it from working correctly.

### 󠀁[Great job! Works with IIS, too](https://wordpress.org/support/topic/great-job-works-with-iis-too-2/)󠁿

 [pjsgsy](https://profiles.wordpress.org/pjsgsy/) February 18, 2023

Only used very briefly so far, but, first impressions = Excellent! It’s the only
cache plugin I found that works well with Wincache/IIS/Windows. It’s very clean 
and simple. The widget is useful, as are the statistics if you enable them. Does
exactly what I want. The only thing I wish it would have as a really nice addon,
is a way to pre-load the cache by visiting each post/page, though I can sort that
externally. Not of failure of this plugin, but, it breaks the ‘simple download monitor’
download links for all files on my site. There is, due to the design of this plugin,
an easy fix (though it errored on my site with a ‘needle’ not found or similar first
time!). Enable ‘Exclusions’ and add ‘download_id’ to the excluded $_GET variables.
Clear your cache, and downloads should work again. This is because download links
are simply sent to the home page with the get variable. Probably a dumb way to do
it, but…

If you use this right and read the instructions – none the better for its purpose.
Combine it with Autoptimze and you’re good to go.
