Yes, it will. It might not be at exactly the time of expiration but it will be within a couple of minutes. It's possible that if you request a new token and re-open the socket within that gap that the disconnected and then connected calls will be skipped. > 2. if i create a channel with the same clientID twice, will that be > considered a new channel (given token is different) or will the token > be the identical ? (and also the same channel) You will get a new token (every call to create a channel, even with the same client id, will result in a new token -- among other reasons, the token encodes the expiration time, so it will obviously change on every call). The channel will be the same, though; if you have two clients connected with tokens generated from the same client id, they will both receive messages sent to that client id. However no guarantees are made of support of multiple connected clients; if you open a new client, other clients connected via tokens generated with the same client id may be (probably will be) disconnected. > 3.

You could have eg. a table of user_ids (from the users API) representing "connected users". -Moishe -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
