If a DRS rule uses a location based rule for a directory such as:
http://foo.com/dir1/dir2
it will match an artifact in a different directory such as:
http://foo.com/dir1/dir20/app.jnlp
due to the code in at end of RuleId.pathIncludes():
        if (rulePath == null || rulePath.length() == 0 ||
                artifactPath.startsWith(rulePath)) {
            pathMatch = true;
        } else {
           Trace.println("Path mistach, actualPath: " + artifactPath,
                   TraceLevel.RULESET);
        }
        return pathMatch;
This is not the case if the location in the DRS includes the trailing slash:
http://foo.com/dir1/dir2/
