How to clear dispatcher cache in Adobe Experience Manager

This article explains how to clear the Dispatcher cache in Adobe Experience Manager (AEM) when recent content changes are not appearing on the live site due to outdated cached content.

Description description

Environment

Adobe Experience Manager (all supported versions)

Issue/Symptoms

After deploying new content changes in Adobe Experience Manager, updates may not be visible on the live website if the Dispatcher cache is serving outdated versions of your content. Clearing the Dispatcher cache for the affected content path ensures that the latest updates are delivered to site visitors.

  • Recent content changes are not visible on the live (publish) site, even though they appear correctly in preview or fragment URLs.

Cause

The Dispatcher cache is serving outdated content for the affected path, preventing new changes from appearing until the cache is cleared.

Resolution resolution

Follow the steps below to resolve the issue:

  1. Identify the Dispatcher cache directory on your Dispatcher server(s). The cache directory is typically configured in the Dispatcher configuration file (for example, /cache or /var/www/html for Linux environments).
  2. Locate the cached files and folders corresponding to the affected content path. For example, if your content path is /content/<site>/, navigate to the equivalent directory within the Dispatcher cache.
  3. Remove or purge the cached files and folders under the affected path from the Dispatcher cache directory. This can be done using file system commands (such as rm -rf on Linux) or through your organization’s approved cache management process.
  4. Ensure you have the necessary permissions and follow your organization’s change management procedures before performing cache clearing operations.
  5. After clearing the cache, access the live site and verify that the latest content changes are now visible.
  6. If the issue persists, repeat the cache purge or investigate further for potential replication or publishing issues.
