//	This javascript tags file downloads and external links in Google Analytics.
//	You need to be using the Google Analytics New Tracking Code (ga.js) 
//	for this script to work.
//	To use, place this file on all pages just above the Google Analytics tracking code.
//	All outbound links and links to non-html files should now be automatically tracked.

//	VKI has made changes as indicated below.		
// 10/22/09 jmallick added tracking for getFile.cfm	and added conditions to trackDocumentLinks for mysiteid and salesiteid
