Marketing program and impression correlation

The Marketing Program link URL and associated Marketing Impression requests for the same Advertisement should contain the same Marketing Program (cm_mmc=) and Marketing Attribute (cm_mmca1-a15) parameter values.

For the following display Ad example linking to your site's home page:
http://data.cmcore.com/imp?tid=17&ci=11111111&vn1=4.1.1&vn2=imp&ec=UTF-8&cm_mmc=
Washington%20Post-_-Display%20Ads-_-Boat%20Insurance-_-Boat_vA_c432&cm_mmca1=
300x250&cm_mmca2=german
The target URL should contain:
http://www.yoursite.com?cm_mmc=Washington%20Post-_-Display%20Ads-_-Boat%20
Insurance-_-Boat_vA_c432&cm_mmca1=300x250&cm_mmca2=german
