This feature determines how an HTTP client's request for a 0-byte cache asset is handled by our edge servers.
| Value | Result |
|---|---|
| Enabled | Causes our edge server to re-fetch the asset from the origin server. |
| Disabled | Restores the default behavior. The default behavior is to serve up valid cache assets upon request. |
Tip: This feature is not required for correct caching and content delivery, but may be useful as a workaround. For example, dynamic content generators on origin servers can inadvertently result in 0-byte responses being sent to the edge servers. These types of responses are typically cached by our edge servers. If you know that a 0-byte response is never a valid response for such content, then this feature can prevent these types of assets from being served to your clients.
Default Behavior: Disabled.
