Description

I needed a way to clear a cache entry off of disk, not just forget about it. The worry was about if you got content on a server that was illegal or a privacy violation of some sort, we wanted a way to be able to tell customers that after this step there was no way that TS could serve the content again. The normal cache remove just clears the directory entry, but theoretically a bug could allow that data out in some way. This was not intended to prevent forensic analysis of the hardware being able to recover the data. And bugs in low level drivers or the kernel could theoretically allow data to survive due to block remapping or mis-management of disk caches.
