    This seems like a totally separate feature. Can we split this from this PR?

> This enhancement adds two options, "fname" and "maxdirs", which can be used 
> to exclude the file-name and some of the directories in the path. The 
> remaining portions of the path are then used as part of the hash computation 
> for selecting among multiple parent caches.
> For our usage, it was desirable from an operational perspective to direct all 
> components of particular sub-tree to a single parent cache (to simplify 
> trouble-shooting, pre-loading, etc.). This can be achieved by excluding the 
> query-string, file-name, and right-most portions of the path from the hash 
> computation.
