--- Comment #3 from Diego Pino <dpino at igalia.com> ---
I've been investigating 'imported/w3c/web-platform-tests/websockets/constructor/011.html'.

The test checks whether subprotocol matching is case-sensitive. The string used as subprotocol is "FOOBAR".

Quoting https://html.spec.whatwg.org/multipage/web-sockets.html (Section 9.3.2):

"protocols is either a string or an array of strings. If it is a string, it is equivalent to an array consisting of just that string; if it is omitted, it is equivalent to the empty array. Each string in the array is a subprotocol name. The connection will only be established if the server reports that it has selected one of these subprotocols. The subprotocol names have to match the requirements for elements that comprise the value of Sec-WebSocket-Protocol fields as defined by The WebSocket protocol."

My understanding is that a valid subprotocol must be a registered value in https://www.iana.org/assignments/websocket/websocket.xml.

The test is only failing when value "FOOBAR" is used. If, for instance, I use a subprotocol from https://www.iana.org/assignments/websocket/websocket.xml, like "soup", the test passes. If I use "SOUP", the test passes too. If I use a subprotocol not in the list (other than "FOOBAR"), like "BARFOO", the test passes too.
