  14  # with some server configurations.  It is required for use of mod_rewrite, but may already
  15  # be set by your server administrator in a way that dissallows changing it in
  16  # your .htaccess file.  If using it causes your server to error out, comment it out (add # to
  17  # beginning of line), reload your site in your browser and test your sef url's.  If they work,
  18  # it has been set by your server administrator and you do not need it set here.
