Hi,
We are building our application on Flex 4 and LCDs 3. The application uses
RTMP protocol to communicate to the server. Request for application server is
routed through Edge server sitting in DMZ. For implementing the logout
functionality, I am invoking logout on the RTMP channel.
The problem occurs when I try to login and logout more than 2 times. For first
two attempts of login-logout, it works as expected. But on third attempt an
error related to invalid FlexSession is displayed on Edge Server console. No
request is forwarded to appln. server
Following is the logout logic
public function logout() : void{
asyncConsumer.unsubscribe();
var token:AsyncToken = asyncConsumer.channelSet.logout();
asyncConsumer.disconnect();
token.addResponder(new AsyncResponder(logoutSuccessCallback,
logoutErrorCallback));
}
private function logoutErrorCallback(event : FaultEvent, token :
AsyncToken = null) : void {
mx.controls.Alert.show("Unexpected error during log out.", "Error");
}
private function logoutSuccessCallback(event : ResultEvent, token :
AsyncToken = null):void {
mainTabNavigator.removeAll();
callLater(showLoginPrompt, [null]);
}
I have not been able to figure out why do I get Invalid FlexSession error third
time ? What extra statements need to be added to clear the Flex Session
infomation from the client.
Following is the error log on edge server for 3rd attempt to login after logout:
