Category: Caching
Purpose: Determines how our edge servers handle a client's request for content that was cached as a 0-byte file.
Valid values are:
| Enabled | Result |
|---|---|
|
Yes |
Causes our edge server to re-fetch the asset from the origin server. |
|
No |
Restores the default behavior. The default behavior is to serve up valid cache assets upon request. |
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.
