LayoutFooterOff allows you turn off any footers that you may have specified. This can come in handy when you have overlapping rules. The following example illustrates this. All of the contents of the virtualhost minus the smurfdance directory will get a footer.
DocumentRoot /usr/local/apache/htdocs/ LayoutFooterTXT "This is a footer." <Directory /usr/local/apache/htdocs/smurfdance/>
