How To Exclude Rank Math Sitemaps from Caching

Caching is one of the easiest and most effective ways to speed up your website. In WordPress, caching is as simple as installing a caching plugin and configuring some basic settings.

However, this usually leads to a problem. When caching is enabled, your website’s sitemap may also be cached,  which is the opposite of what should happen. Since a sitemap should always be up to date with the pages, posts, and custom posts on your website, caching it defeats the purpose.

That is why we’ll show you how to exclude the sitemap generated by Rank Math from being cached. We will cover the most popular caching plugins, but the methods should also work for other plugins. 

Let’s begin.

1 htaccess

Before making any changes to your cache plugin’s settings, you should add a rewrite rule to your .htaccess file and confirm if it resolves the issue. To do that, navigate to Rank Math SEO → General Settings → Edit .htaccess from your WordPress dashboard. 

Edit .htaccess file with Rank Math

Editing your site’s .htaccess file can break your site if you make any mistakes. Hence, Rank Math displays a warning and keeps the text area disabled to avoid any accidental edits.

You can add the below code to the text area once you click the checkbox below the warning. Once done, click Save Changes

Note: You can use the htaccess tester tool to debug and ensure the rewrites are correct before adding them to the .htaccess file. 

RewriteEngine On
RewriteRule .* - [E=Cache-Control:no-cache]

The next step is to confirm whether your sitemap is excluded from the cache. If not, proceed with the below steps to change your cache plugin’s configuration.

2 WP Rocket

To exclude your sitemap from being cached by WP Rocket, head over to Settings → WP Rocket → Advanced Rules → Never Cache URL(s). Once done, enter the below code snippet and save your settings.


3 W3 Total Cache

To exclude Rank Math’s sitemap from being cached by W3 Total Cache, head over to Performance → Page Cache from your WordPress dashboard. Then, enter the below code in the Never cache the following pages settings.  Once done, click Save all settings to save your changes.


The above code is a simple regular expression (regex) that tells W3 Total Cache to exclude all XML and XSL files with “sitemap” in the name from being cached.

Since W3 Total Cache supports multiple caching methods, you should ensure that none caches the sitemap. Here is how to do that for the different cache types inside W3 Total Cache.

3.3 404 Error Exception List

W3 Total Cache also caches 404 errors on your website, which can lead to the sitemap getting cached. To prevent this, head over to Performance → Browser Cache. Then, add the code snippet to the 404 error exception list settings, as shown below. Once done, click Save all settings.

Note: Recent versions of W3 Total Cache have this code snippet added to the 404 error exception list by default. In that case, you don’t need to add another code snippet.

To do that, log into your Cloudflare account and select your website. Then, navigate to Rules → Page Rules and click Create Page Rule, as shown below.

9 Transient Cache

Sometimes the sitemap can be affected by a server-level cache. In such a case, you can add the below filter to your theme’s rank-math.php file to exclude your sitemap from being cached.  You can refer to this guide on adding filters to a WordPress site.

 * Filter if XML sitemap transient cache is enabled.
 * @param boolean $unsigned Enable cache or not, defaults to true
add_filter( 'rank_math/sitemap/enable_caching', '__return_false');

10 Other Caching Plugins

If you’re using other caching plugins, you’ll have to do some research to find a solution. Most caching plugins allow you to disable your sitemap from being cached, so you wouldn’t have much trouble finding a solution. 

Also, the code snippets we shared are regular expression (regex) codes, so any plugin that supports regex will accept the code. If you can’t find a solution, contact the plugin developer or your hosting provider for support.

Next Steps

No matter what caching plugin you use, ensure to save your changes and empty your cache after you’ve made these changes. Make sure to double-check your settings were saved, as you might navigate away from the page without saving your settings.
