Description

When you send a message using IWebSocketConnection.sendMessage() and an exeption is raised somewhere during processing of this message you can get the following exception (the orignal exception is lost):

This is because WebPageRenderer by default calls redirectTo method. So it looks like WebSocketResponse.sendRedirect() should not throw exception in the default implementation?
