The cookie stored in the browser, the namespace of the cookie-name is: domain+path, regardless of the port number .

 

which is:

1. Under the same domain and under different paths, cookie-names with the same name can exist without overlapping each other.

2. Under the same domain, if the path is the same, even if the port number is different, the cookie-name of the same name will cover each other.
