If an AuriStorFS client were deployed these lookups could be disabled
using the following yfs-client.conf configuration file entry.

    [afsd]

        ignorelist-afsmountdir = .htaccess

Instead of attempting to resolve a cellular mountpoint for
/afs/.htaccess Apache would be provided a zero-length file.

Happy Holidays.
