[undertow-dev] Can't get customed header and attributes in the websocket handshakeheader.

Hi, We registed a web socket handler in the server, waiting for the clients to connect. According to the usiness, we need to identify (or mark) a client when it do handshake with the server, so I tried to set some customed headers in the handshakeheader, just like: WebSocketConnectionManager manager = new WebSocketConnectionManager( webSocketClient, webSocketHandler, "ws://localhost:8080/websocket/myHandler"); manager.setAutoStartup(true); *manager.getHeaders().add("myHeader", "1234567");* return manager; I supposed to retrieve it from the WebSocketSession in the serverside, but I can't get it. it is ok in the jetty server 9. The server we used: wildfly 8.0.3 Release The client dependencies: <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>4.0.3.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-websocket</artifactId> <version>4.0.3.RELEASE</version> </dependency> <dependency> <groupId>javax.websocket</groupId> <artifactId>javax.websocket-api</artifactId> <version>1.0</version> <scope>compile</scope> <optional>true</optional> </dependency> <dependency> <groupId>io.undertow</groupId> <artifactId>undertow-websockets-jsr</artifactId> <version>1.0.3.Final</version> </dependency> This issue blocked me for some days, could you please help to figure out what's the matter, and it is really appreciate if you can give some advice to achieve that. Thank you very much! Sincerely yours, Lynn
