How long is the content cache in the SSD?
Default system settings, OS/Application update content cache would be kept for 7 days and the other cache content would be kept for a month.
I turned off the device last Friday after the test. However, I play the same video today and I see that there is WAN activity in the real-time bandwidth page.
However, the default expired time settings for each cached content can be overwrite by the web server “Expires Response Header” to support dynamic content update.
For more information regarding to the “Expires Response Header” for the web server, you may refer to the URL below:
Does shutdown of the device also clear the cache?
Rebooting/Shutdown the unit will not help to clear the cache
I know that the content can be cleared manually or automatically?
Automatic web cache content clearing will happen for the below events:
- Cache Content expired base on the default expiring time or “Expires Response Header”
- When the storage is full, MFA would follow LRU policy (least recently used) to replace old cache objects. This means objects which have not been accessed for the longest time are removed first
Manual web cache content clearing can be initiated by administrator. For more information please refer to the screenshot attached.
