Here is a nice little example of testing for online and offline within Apollo. It is very basic.
Test it by either hitting the Test Connection button or by pulling your cable on disconnecting your wireless.
Here is what is occurring within the application:
on creationComplete Shell.shell.addEventListener(Event.NETWORK_CHANGE,onNetworkChange); onNetworkChange test the connection. Here is the contents of the test connection function.
when the HTTPStatusEvent.HTTP_STATUS Event is broadcast statusChanged is called

var headRequest:URLRequest = new URLRequest();
headRequest.method = "HEAD";
headRequest.url = "http://blog.everythingflex.com";
var response:URLLoader = new URLLoader(headRequest);
response.addEventListener(HTTPStatusEvent.HTTP_STATUS,statusChanged);
response.addEventListener(IOErrorEvent.IO_ERROR,error);
headRequest.method = "HEAD";
headRequest.url = "http://blog.everythingflex.com";
var response:URLLoader = new URLLoader(headRequest);
response.addEventListener(HTTPStatusEvent.HTTP_STATUS,statusChanged);
response.addEventListener(IOErrorEvent.IO_ERROR,error);
The statusChanged fuction checks the status code and sets disconnected if code is 0
if IOErrorEvent.IO_ERROR is broadcast
we assume the connection is broken
Thats it. There are additional URLLoader events that can be checked but I haven’t included them in this example. Check the documentation for details on these events. Here is the results:

Thanks for this. I have basically put this code into it’s own class and am calling it like:
var tmpStatus:NetworkStatus = new NetworkStatus(url_tocheck);
trace(tmpStatus.getStatus());
tmpStatus.getStatus() keeps returning a false. It’s as if it is being executed too quickly. is there a way to make sure the initializing of the class fully executes before proceeding to the next line of code?

Very handy, I knew it would be simple to do but it’s nice to know I don’t have to figure it out myself when I come to need it! Thanks mate

Ran into problem with this example. Attempted a complete removal of Apollo and a re-install of AIR. Still ran into a compatibility error.

Yes, this is old code that was built for Apollo, it will not run under AIR.

After a LOT of effort for a c# programmer, a little update

OOPS CAN’T POST THE CODE !
basically import flash.desktop.Native Application;
in the init function replace the shell call with
Native Application.native Application .add Even tListener(Event.NETWORK_CHANGE,o nNetworkChange);
all else should wok fine

Sorry you wasted so much time with an old Apollo sample. Check out my ConnectionManager class in the EverythingFlexAIR swc:
