title: Overwriting user web browser's cookies
body: <p>Is overwriting visitor cookies possible ?</p>
  
  <p>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 ?</p>
  
  <p>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.</p>
  
  <p>Differences between the marked duplicate question: I am talking about editing existing cookies not URL redirection </p>
