	This code uses a CF User Defined Function and should work in CF version 5.0

	Also if you are hosting your site at an ISP, you will have to check with them
	to see if the use of <CFEXECUTE> is allowed. In most cases ISP will not allow
	the use of that tag for security reasons. Clients would be able to access each
	others files in certain cases.
