The path rule will, for matching clients (if group is defined), replace the requested directory (reqdir) with a new destination directory (destdir) on each access.
The path rules are matched in the order they were added (oldest first) and only the first matching rule is applied.
The path rule with reqdir and group is created or updated with destdir. The group defines a subset of clients that this rule applies to. If no group name is given, the path rule is valid for all clients.
