On the browser side I had automatic reconnects implemented, whenever the Websockets connection was closed.
But now I am trying to detect, that a player is already connected in another browser tab and then send a custom close status 4000 from Jetty (so that automatic reconnect is disabled there and a dialog is displayed to the user, offering to reconnect):
// called by the onWebSocketText Jetty-callback
private void handleLogin(String username, String password) throws Exception {
// check username + password and then send the player her/his open games
mSession.getRemote().sendStringByFuture(mServlet.getGames(mUid));
// if oldSession is not null and still open,
// then the player has several browser tabs open or
// uses the mobile and the desktop app at the same time
Session oldSession = SESSIONS.put(mUid, mSession);
try {
oldSession.close(4000, "another game session detected");
oldSession.disconnect();
} catch (Exception ex) {
// ignore
}
However this only works sporadically, I rarely see the code 4000 in the browser.
Is this caused by the half open connections too?
Thank you
Alex
