Does anyone know a standard way to keep alive the http session as long user has open the flex app in the browser?
I played around with the polling mechanism of blazeds. But it had no affect on the http session.
There is no standard way of doing this. We do a ping-pong with the server every n-seconds (check the AS3 Timer class), where n must be lower than the session timeout. It's best to keep your session timeout as low as possible to reduce memory consumption on the server, especially when you have a lot of concurrent users.
