Google App Engine Channel API MESSAGE QUEUES

Question

If a client is connected and then disconnects - say his connection is lost for 5 mins; does the server queue the messages that can't be delivered?

On the local development server this seems to be the case?

If this is the case in production - how long are the messages queued for?

Thanks

In production the messages are dropped if your server receives the /_ah/channel/disconnected/ POST.

In practice there's a tiny bit of caching. If you eg. lose your connection very briefly because your wifi connection drops, a message sent during that time could be queued up and delivered. But you shouldn't get the disconnect POST in that case.

The disconnect message arrives where on the client or on the server, thanks. – spidee Jun 27 '12 at 14:12
I'm talking about the POST to /_ah/channel/disconnected/ that happens if you enable channel_presence in inbound_services. – Moishe Lettvin Jun 27 '12 at 14:17
