Quick answer, if you want a reason message, you have to specify a valid, can be sent over the wire, close status code.
Detail answer, The WebSocket spec (RFC 6455, Section 5.5.1. Close) https://tools.ietf.org/html/rfc6455#section-5.5.1 A Close frame MAY contain a body. If there is a body, the first two bytes of the body MUST be a 2-byte unsigned integer representing the status code. Following the 2-byte integer, the body MAY contain UTF-8 encoded data with reason. And the status codes allowed to be sent over the wire are in Section 7.4.1. https://tools.ietf.org/html/rfc6455#section-7.4.1 Some status codes are not allowed to be sent over the network. (They essentially are internal status codes). -- Joakim Erdfelt <[email protected]> webtide.com <http://www.webtide.com/> Developer advice, services and support from the Jetty & CometD experts eclipse.org/jetty - cometd.org On Tue, Oct 30, 2012 at 1:22 PM, Brandon Mintern <[email protected]>wrote: > When a connection is closed with a message and closeCode <= 0, the message > is not sent at all.
