WordPress Caching Plugin WP Super Cache Download and Setup Tutorial

WP Super Cache is a WordPress caching Plugin. Is it necessary to use WP Super Cache when building your own website? The answer is yes, it is necessary. Installing a caching Plugin can help the website run faster and use fewer server resources, so caching Plugins should be considered essential for WordPress.

WP Super Cache introduction

WP Super Cache helps dynamic WordPress blogs generate static HTML files. After generating HTML files, it avoids fetching data via PHP every time the website is accessed, instead directly reading the cached HTML files, which helps improve website access speed and reduce server resource usage.Static cache files can be provided to the following users:

• Users who are not logged in.
• Users who have not commented on your blog.
• Or users who have not yet viewed password-protected posts.

After enabling caching, 99% of your website visitors will access static HTML files. A cached file can be accessed multiple times. WP Super Cache delivers cached files in 3 ways (sorted by speed):

1. Expert. The fastest method uses Apache mod_rewrite (or any similar module supported by your web server) to serve „super cache“ static HTML files. This completely bypasses PHP and is very fast. However, this method requires you to have server administration permissions and know how to modify the configuration.
2. Simple. PHP can serve WP Super Cache„s static files; this is the recommended method for using the plugin. When enabled, the plugin generates “supercached„ files, which are almost as fast as the mod_rewrite method. Configuration is easier since no changes to the .htaccess file are required. You still need a custom permalink. You can keep certain parts of the page dynamic in this caching mode.
3. WP-Cache caching. This is mainly used to cache pages for known users, URLs with parameters, and feeds. Known users are logged-in users, visitors who have commented, or visitors who should see custom per-user data. This is the most flexible caching method and is slightly slower. If super cache is disabled, WP-Cache caching will also cache visits from unknown users. You can also include dynamic parts in pages in this mode. This mode is always enabled, but caching for known users, URLs with parameters, or feeds can be disabled. If you only want to use WP-Cache caching, set the constant „DISABLE_SUPERCACHE“ to 1 in wp-config.php.

If you are not comfortable editing PHP files, use Simple mode. Easy to set up and very fast.

WP Super Cache recommended settings

1. Use Simple mode caching.
2. Compress pages (do not select if the server itself has compression enabled).
3. Do not cache pages for known users.
4. Cache rebuild.
5. CDN support.
6. Extra homepage check.

Garbage collection is the act of cleaning up expired and stale cache files. There is no fixed value for the expiration time; enter it based on your actual situation, recommended to be above 1800 seconds. Consider removing the content of the „Rejected User Agents“ text box and allow search engines to cache files for you. Preload as many posts as possible and enable „Preload Mode.“ Garbage collection of old cache files will be disabled. If you are not concerned about updates to sidebar widgets, typically set the preload interval to 2880 minutes (2 days) so that all posts are not recached too frequently. When preloading occurs, the cache files for posts to be refreshed are deleted and then regenerated. After that, garbage collection is performed on all old files to clear stale cache files. Even with Preload Mode enabled, cached files will still be deleted when a post is modified or a comment is posted.

WP Super Cache setup tutorial

1. After installing WP Super Cache, enable the caching function.After enabling, you can test to see if it is successfully generated. If it cannot be generated, it is likely due to incorrect folder permissions; please set them to 755. 2. In Advanced, select Simple mode, check Extra homepage check, and choose other items based on your actual situation. Then test the website using a browser's private/incognito mode. As long as there are no issues, it is OK.3. It is recommended to enable the pre-caching function.4. Visit the website and view the website source code. If the page is successfully cached, there will be a prompt, as shown in the figure below.After enabling WP Super Cache for your website, you may not experience a significant speed improvement yourself because caching is not enabled for logged-in users by default. You can use a browser's private/incognito mode to test the speed difference between enabling and disabling caching.
