When changes are made to a page but the old version is still seen by the client, it is often due to the Dispatcher cache still serving the old content. The Dispatcher cache stores HTML pages and assets to reduce the load on the AEM server and improve performance. Here are the steps to resolve the issue:

Clear the Dispatcher Cache:

Navigate to the Dispatcher cache directory on the server.

Identify the cached files related to the page in question.

Delete the relevant cached files or clear the entire cache if necessary.

Access the Page Again:

Once the cache is cleared, the new version of the page will be served from the AEM server when accessed again, reflecting the recent changes.

References:

AEM Dispatcher documentation on cache invalidation and management.

Best practices for managing the Dispatcher cache to ensure updates are reflected promptly.

The cache header that will prevent a file from getting cached in dispatcher isResponse.setHeader("Cache-Control: no-cache").

Cache-Control Header: The Cache-Control header is a directive that specifies caching policies in both requests and responses.

no-cache Directive: Setting the Cache-Control header to no-cache instructs the dispatcher and other intermediaries not to cache the response.

Implementation: By including this header in the response, AEM ensures that the dispatcher retrieves the latest version of the content directly from the AEM instance rather than serving a cached version.
