This is possible using built in methods within the uTag code. (utag.loader.SC).
A simple example would be:
This would set a cookie with the name utag_test and the value:
This would add the values you have defined in the object to the utag_main cookie. You can use any name for the cookie but if you wish to pass multiple values in the format of an object, the cookie name needs to be prefixed with "utag_" else the function will only accept a non-object argument like so:
utag.loader.SC("HRS", "a string");
This will set a cookie with the name "HRS" and the value "a string".
If you wish we can discuss this in more detail on our call later today.
