Stale Cache

The Stale Cache feature in the Medianova Cloud Panel allows you to serve stale (previously cached) content when certain HTTP error codes or an "Updating" status is encountered. This ensures uninterrupted availability of content during temporary origin server issues or while content is being updated.

Key Features

• Maintain Availability: Serve cached content even when the origin server experiences temporary issues or returns specific error codes.

• Customizable Error Triggers: Select which HTTP error codes or the "Updating" status should activate the use of stale cached content.

• Improved User Experience: Reduces downtime and ensures users continue to access content even during backend disruptions.

Supported Triggers

You can configure the system to serve stale cached content when any of the following statuses are detected:

• Updating: Triggered when content is in the process of being updated.

• HTTP_500: Internal Server Error.

• HTTP_502: Bad Gateway.

• HTTP_503: Service Unavailable.

• HTTP_504: Gateway Timeout.

• HTTP_403: Forbidden.

• HTTP_404: Not Found.

• HTTP_429: Too Many Requests.
