I have created a simple footprint based on browser type. I have verified that every time when I was selecting the footprint it was showing the same claim store and there was no change in triggers. Can anyone suggest what I am missing or where can I look to get the root cause..
The most likely reason is that it is not whitelisted in cd_ambient_conf.xml. You will need to make sure that the IP and the user account (if applicable) is whitelisted -- as well as the new claim.
For more information, have a look at the following pages in the SDL Tridion 2013 SP1 documentation:
Do you have the footprint cartridge configured in your ambient data configuration, as per step 9 of Quick Guide to installing Experience Manager (Session Preview)?
Mukesh as Peter and Devid suggested please check your cd_ambient_conf.xml file. But before you move to the detail check just verify once again have you updated your claim into that cd_ambient_conf.xml file under the GloballyAcceptedClaims node ?
