In RFC6455 section 10.3, it explains why they have made clients mask their outgoing frames (so that a malicious server cannot manipulate a client into sending something in plaintext, as the message could be a HTTP request which could be us… Continue reading Cache poisoning from rfc6455 (WebSockets) not requiring server message to be masked?
