This determines how long a cached resource can be used after it becomes stale This is a time unit value and can be written in human readable form (e.g. "1 day", "3 weeks" etc.) If just a number is supplied, it will be interpreted as SECONDS Min: 0 milliseconds, Max: 20 years |
| default_stale_if_error | no | time | 1 day | This parameter was introduced in version 7.25.0 Used to define the default stale-if-error value when fetching a resource. stale-if-error determines how long a stale resource can be used if the resource is available in the cache but cannot be fetched This is a time unit value and can be written in human readable form (e.g. "1 day", "3 weeks" etc.) If just a number is supplied, it will be interpreted as SECONDS Min: 0 milliseconds, Max: 20 years |
