Can server side AS defines shared variable between all instances?

I want to create variable that share between all instances of application.

For example. I want to share number of connections.

rtmp://example.com/testApp/instanceA : 2 connections

rtmp://example.com/testApp/instanceB : 3 connections

=> 5 connections.

I tried to set property to "application" object in AS.

/opt/adobe/ams/applications/testApp/testApp.asc application.onConnect = function(cli) {   applicaion.counter += 1;   trace(application.counter); }

but "application" object is shared by same instance, isn't shared by application.

so testApp/instanceA output 2, and testApp/instanceB output 3.

# It's just example. I know that Administration API has getServerStats for count connections.

Thanks.
