Are cookies shared across ports?

Are cookies shared across ports?

Similarly, cookies for a given host are shared across all the ports on that host, even though the usual “same-origin policy” used by web browsers isolates content retrieved via different ports. Cookies do not provide isolation by port.

Is Port part of domain?

Domain names don’t refer to specific ports. You can certainly run a web server on port 8088 if you like. The port number would have to appear in the URL, e.g. http://somehost.example.com:8080/some/page .

Can a domain set cookie for another domain?

Setting cookies for another domain is not possible. If you want to pass data to another domain, you can encode this into the url. You can’t, at least not directly. That would be a nasty security risk.

How to handle multiple cookies with the same name?

If multiple cookies of the same name match a given request URI, one is chosen by the browser. The more specific the path, the higher the precedence. However precedence based on other attributes, including the domain, is unspecified, and may vary between browsers.

How are cookies set on the same server?

If a cookie is writable by a service on one port, the cookie is also writable by a service running on another port of the same server. From this, I would expect cookies set for example.com:3000 to be sent to example.com:4000 also.

Can a cookie be shared with multiple browsers?

Theoretically, you can specify port number in the domain and the cookie will not be shared. In practice, this doesn’t work with several browsers and you will run into other issues. So this is only feasible if your sites are not for general public and you can control what browsers to use.
