John Rushford commented on TS-4707:
-----------------------------------

@pbchou - Discussed this PR 834 with @zwoop and @jpeach.  We're in agreement that instead of adding new configuration parameters to parent.config, that you can accomplish this manipulation of the filename and directories eith the new API calls in PR 1009.

> 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.
