*Copyright 2000-2004,Coremetrics 4.0.18 $Revision: 125080 $
*CMX Version for all sites 
*
* Date            Modifier        Description
* 20070105		Andy Cabezas    Gomez traffic blocking
* 20070109		Hutch White        Add cm_ref detection for Referring URL forwarding
* 20070118		Tim Gilbert     Falling back to cmrf if cm_ref not found - this is needed for Flash redirection which uses cmrf.
* 20070130		Tim Gilbert     Using cm_ref for redirects again; misc cleanup.
* 20070220		Hutch White		Make ParseRef check for cm_ref case insensitive
* 20070608		Hutch White		Added conversion, element, all manual tags, trackimpressions RS
* 20071030		C Williams		Added code to ProductTag to prevent duplicate viewset prefixes eg, E:E:ABC. This code is maintained by WSI to handle Akamai caching issues.
* 20080430		MOCHOA			Enabled MovieTime Tagging Function ; Disable Impression Tracking
* 20080516		HWHITE			Add cm_em parameter checking
* 20080801		LHIBBARD		Changed cm_em to not be a page view, added BV tagging
* 20090403		ETOWB			Cleaned up comments; converted to MakeTag version; added attributes;
*						Important Note:  Outstanding decisions regarding shop attribute de-duping must be resolved before shop attributes are used.
* 20090724		ETOWB			Fixed Issue with Order tag extra_field 1 being hardcoded to "N"
*						Note:  Shop Attribute de-duping question is still outstanding.
*               CBWILLIAMS      Removed logic for campaigns per CHR-157
