1. Multiple requests can be sent to the same domain name with hair?
(2) from one client to another client, how data flow
3. The same-origin policy is a protocol, domain name, port number even across different domains, if I request an IP address can be directly?

CodePudding user response:

1. The different domains of multiple requests can be sent together
2. The client sends to the server, the server to the client, the second, the client sends the server, client 2 pull server, the server returned to the client 2 latest information
3. No, different IP even cross domain

CodePudding user response:

Different port is also cross domain
