Does the cache expiration time in Attachment Manager (from TIBCO Spotfire Server Configuration Tool > Configuration Tab) take precedence over the Information Link cache timeout, or vice-versa?

Does the cache expiration time in Attachment Manager (from TIBCO Spotfire Server Configuration Tool > Configuration Tab) take precedence over the Information Link cache timeout, or vice-versa?

Between the cache expiration setting in Attachment Manager (from TIBCO Spotfire Server Configuration Tool > Configuration Tab) and the Information Link cache timeout, which one takes precedence? For the Information Link cache timeout and cache expiration in Attachment Manager, they both are active. So the setting that is shorter will be hit first and takes precedence over the other in determining whether the cache has to be purged. 

For example:

---------------------------------------------------------------------------------------------------------------
If I have an Information Link called "Sales" and the cacheable box is checked with the timeout entered at 72000 seconds (20 hours) and the cache expiration time is set at 43200 seconds (12 hours) in Attachment Manager, will the data stored in cache (on Disk in the filesystem on the Spotfire Server) for the Information Link expire in 20 hours, or 12 hours?
---------------------------------------------------------------------------------------------------------------

Answer: 12 hours.

-----------------------------------------------------------------------------------------------------------------

Conversely, if the Information Link cache is set at 12 hours and the Attachment Manager cache is set at 20 hours, when will the cached Information Link data expire?

------------------------------------------------------------------------------------------------------------------

Answer: 12 hours.
