Error Status Code Cache Expiration

The Error Status Code Cache Expiration feature in the Medianova Cloud Panel allows you to cache specified error codes (such as 404, 500, etc.) for a defined duration. By doing so, you can control how long error responses are stored in the CDN cache, reducing the number of requests sent to the origin server. If you don't want certain error codes to be cached, simply remove their definitions, and requests for those error codes will be sent directly to the origin server. However, if the content has already been cached, the cache duration will remain in effect until it expires.

Key Features

• Cache Error Status Codes: You can define a set of error codes (e.g., 404, 500, etc.) and specify a cache duration for each. This helps in reducing the load on your origin server by caching error responses for a certain period.

• Removal of Caching Definition: If you remove a cached error status code definition, requests for that error will bypass the CDN cache and be sent directly to the origin server. However, cached content will not be affected immediately and will remain in the cache until the cache duration expires.
