Detailed Description

Proxy backend that manages file layout rewriting for FileRepo.

LocalRepo may be configured to store files under their title names or by SHA-1. This acts as a shim in the latter case, providing backwards compatability for most callers. All "public"/"deleted" zone files actually go in an "original" container and are never changed.

This requires something like thumb_handler.php and img_auth.php for client viewing of files.

1.25
