AUTHOR		Doug Scamahorn

DATE       	NAME           	DESCRIPTON
02/23/2007 	Doug Scamahorn  Initial creation.
05/10/2007	Doug Scamahorn	Added tracking of internal and external links as well as ability to allow sitepass function to fire for external links other than msds.xhq.lilly.com.
09/25/2008	Ben Rondot  	Commented out the tracking of internal and external links as well as ability to allow sitepass function to fire for external links other than msds.xhq.lilly.com. Now all links which need the sitepass interstial page will need to be noted in the link itself. Reason: Locations is now directed to the Elanco.com site and no interstital is needed.
04/08/2009  Dan Laughlin	Removed comments surrounding the tracking of internal and external links as well as ability to allow sitepass function to fire for external links other than msds.xhq.lilly.com.
