Class JsrWebSocketFilter

java.lang.Object

io.undertow.websockets.jsr.JsrWebSocketFilter

All Implemented Interfaces:

javax.servlet.Filter

public class JsrWebSocketFilter
extends Object
implements javax.servlet.Filter

Filter that provides HTTP upgrade functionality. This should be run after all user filters, but before any servlets.

The use of a filter rather than a servlet allows for normal HTTP requests to be served from the same location as a web socket endpoint if no upgrade header is found.

TODO: this needs a lot of work
