Is overwriting visitor cookies possible ?
Here is the scenario, user visited website A and website A dropped cookies on user's web browser after that user went to my website - am I able to overwrite user's cookies of other website by user visiting my website ?
To simplify it is to change user cookies of an affiliate link abc.com/aaa to abc.com/bbb just by them visiting my site.
