The problem of incomplete removal of cookie under IE11

after the user logs in, the front end stores the user information in cookie, and the Http request header automatically carries the cookie information. However, when all caches are cleared in the browser settings, it is found that there is still cookie information in the request header. May I ask why this problem occurs? How to solve it?
