Configurable cache options for Office Online Server / Office Web Apps Server on-premises
Currently there are no options in on-premises Office Online Server or Office Web Apps Server farm to configure cache expiration interval, or even flush the cache manually if ever needed.
Although there seems to be a DiskCacheForcedDeletionAgeDays property value inside the product, it is not exposed to be configured.
We've also experienced a few times the need for a cache flush. There is no API / PowerShell commands for doing so, we've got around it by deleting cache folders, but is kinda rude action to do. A command for safely disk and/or memory cache flush would also be welcome.
Does this solution apply to SharePoint 2016?
