Description

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.
