Iphone subscription question

[DarioCrivelli]

How can you identify whether the received updates are from 410 or 811?
Only by the item reference supplied by the API interface, or also by the field values?

I see that the subscription and unsubscription requests are very well separated,
so it doesn't seem likely that updates from a previous subscription are delayed.
What about the "timestamp" field of the updates that shouldn't have occurred?

For a server-side check, you could enable logging of the update flow.
Please set the priority of the LightstreamerLogger.subscriptions and LightstreamerLogger.pump categories to DEBUG.
This will allow you to trace the unexpected update events.

Thanks DarioCrivelli,

I found the cause of problem. Because our Iphone client created two sessions and both subscirbed to Lightstreamer server with same window ID. One subscribed item A and the other subscribed item B. Our Iphone client use window ID for identify each item. Therefore I received two items mixed. It seems to be our bug. Thanks for your help.
