Good point. I was thinking of the index, but there's no need to impose
those restrictions on the files within. Perhaps they were trying to
control cache behaviour on the index and just didn't bother turning it
off for the files in the directory?

A .htaccess file for cache control in the sigs/ directory could well
cause exactly this.
