By any client-side ECMAScript implementation in that environment (there is 
no javascript¹).

Look for assignments to “document.cookie”, where the right-hand side 
contains “0” or “new Date()”.  A way to delete a (non-HTTP-only) cookie is

  document.cookie = "cookie_name=…;max-age=0";

or

  document.cookie = "cookie_name=…;expires=" + (new Date()).getUTCString();
