-// WebSocketHandshake*Handler handles WebSocket handshake request message
-// from WebKit renderer process, and WebSocket handshake response message
-// from WebSocket server.
-// It modifies messages for the following reason:
-// - We don't trust WebKit renderer process, so we'll not expose HttpOnly
-//   cookies to the renderer process, so handles HttpOnly cookies in
-//   browser process.
