Why is authorization replacing the wrong cookies?

Question

HTTP Cookies

The service (localhost:3000) is locally raised and two sites also work locally with this service.
One on the port localhost:8003 , the second localhost:8002 .
From the beginning, one site is authorized (on the localhost:8002/ domain) , it receives cookies with a token.
Then the second one ( localhost:8003 ) is authorized, it also receives cookies with a token, but these cookies are replaced by cookies from localhost:8002/.
I am using chrome browser.
Why is this happening? And how to fix this problem?

Answer 1

Cookies work per domain, not per port. Well, respectively, they are overwritten, try to display the data of the $_SESSION array on two domains after authorization, if everything is fine, remove the authorization on the second port. And yes, don't do that on the combat site)
