there is a problem: the token logged in by the user has the path:"/"; of cookies cut to system A, the token of system A has path:"/a", cut to system B, and the token of system B has path:"/B". When I quit in system A, I erased the data in cookies at the same time. Now I can only delete the user token and the token, of system A, but not the cookies in system B. What should be done
