This header determines whether a page has been cached previously or needs to be regenerated by the server.

When the cache header is not detected, some of the possible consequences include:

• Longer page load time: The data is not retrieved from the cache, so the server needs extra time to process the page.
• Increased server load: Servers have to work harder to process page requests that can actually be completed faster by caching.
• Declining user experience: Site visitors may be frustrated with slow load times, especially on devices with slow connections.

common causes of litespeed cache headers not detected

1. Improper Plugin Configuration

LiteSpeed Cache has a very flexible and complete setup. However, incorrect or unoptimized settings could be the main cause of cache headers not working.

2. Conflict with other plugins

WordPress has thousands of plugins available. Certain plugins, especially those with regard to security or cache management, can cause conflicts with LiteSpeed cache.

3. Not using the LiteSpeed server

Although this plugin is compatible with non-LiteSpeed servers such as Apache or Nginx, its best performance can only be achieved on LiteSpeed servers.

4. HTTP headers are not set properly

Incomplete or misconfigured HTTP headers may cause the plugin to be unable to detect the existing cache.

5. Improper cache-control settings

Arrangement Cache-Control In .htaccess files or at the server level is also often the main cause of this problem.

6. Problems with CDN or Proxy

If you are using a CDN (Content Delivery Network) or a proxy server, it is possible that the cache header is changed or removed by the system.

How to Solve Litespeed Cache Header Problem

Here are the detailed steps to ensure that the LiteSpeed cache header can be detected correctly:

1. Verify the server used

• Make sure your server supports LiteSpeed. You can check the server type through a tool like phpinfo() or directly ask your hosting provider.
• If you’re not using a LiteSpeed server, consider switching, because this server is specifically designed to work optimally with the LiteSpeed Cache plugin.

2. Update the LiteSpeed Cache Plugin

• Plugins that are not updated can cause various compatibility issues. Make sure you use the latest version by downloading from WordPress Repository.
• Updates also usually include bug fixes that may be relevant to your problem.

3. Reconfigure the plugin settings

Perform an in-depth check on your plugin settings:

• Open the WordPress dashboard and enter the menu Litespeed Cache > Settings.
• Enable all important caching features such as Enable cache, cache logged-in users, and Mobile cache.
• If you use the feature ESI (Edge Side Includes), make sure that the settings are in accordance with the needs of your site.

4. Check and edit the .htaccess file

The .htaccess file is an important configuration file for Apache-based servers. To make sure LiteSpeed Cache works fine, add the following rules:

<ifmodule litespeed>
    Cacheenable Public /
    Rewriteengine on
    RewriteRule .* - [E=Cache-Control:max-age=3600]

Save the file after making changes, then check if the problem is resolved.

5. Disable conflicted plugins

Other plugins that handle caching or security may interfere with the LiteSpeed Cache function. How to identify it is:

1. Disable all plugins except LiteSpeed Cache.
2. Re-enable the plugins one by one and check if the cache header remains detected.

• X-LiteSpeed-Cache: Hit
• Cache-Control: max-age=...

If this header does not appear, there may be a problem with the plugin or server settings.

7. Check CDN or Proxy Settings

If you are using a CDN such as CloudFlare, make sure that the settings do not clear the cache header. You may need to adjust the caching settings in the CDN.

8. Contact the hosting provider

If all the above steps are not successful, contact your hosting provider. They can help you check server settings and provide solutions.
