blazeds how to understand if the session is timed out

Hi my aim is to catch when the session is invalidated and send message to all destination that the FlexClient subscribed that the client wiht id .... has disconnected.

I implemented a service which listens for sessionCretaed,sessionDestroyed,clientCreated,clientDestroyed,messageClientCreated,messageClientDestroyed.

Problem is that i want to catch messageClientDestroyed and send to that destination a message that the user has disconnected.But blazeds destroys messageClient when you add a subtopic.So how to understand that if session is invalidated and all messageClient are being destroyed or the user just enter another place and add a subtopic to his consumer.

I'am also open for other solutions to implement that mechanism.When user disconnected by session timeout or closed the site browser etc. i wanna catch it and send a message to subscribed destinations.

thank you.

I am not a master on this topic but I believe you have to tune into the Flex session lifecycle event, FlexSessionListener after a d/c.

If your client is leaving because they want to, on the flex side you invoke disconnectAll() on the ChanelSet so that Blaze DS will clean up resources explicitly.

If your client is leaving because of timing out, you can configure the channel definition to use invalidate-session-on-disconnect = true

These two should trigger the FlexSessionListner.sessionDestroyed(). The parameter for this method is a FlexSession object where you can extrapolate what you need.
