Online/Offline Detection in Flash

I am working on a project where I would like Flash to be able to determine whether the browser is serving content over HTTP or on the user’s local drive.

I actually found the key bit of code for this from a great resource that BH has sent out a few times: Mr. Doob!

I expanded his code to redirect to a file depending on what environment it believes it is in:

var localMode : Boolean = loaderInfo.url.indexOf("file") == 0;

trace(localMode);

var serverMode : Boolean = loaderInfo.url.indexOf("http") == 0;

trace(serverMode);

 

if (localMode == true) {

       loadPlayerInterface('default.html')

}

if (serverMode == true) {

       loadPlayerInterface('default.asp')

}

 

function loadPlayerInterface(myFileName:String):void {

       var url:String = myFileName;   

       var request:URLRequest = new URLRequest(url);   

       try {

              navigateToURL(request, '_parent');   

       } catch (e:Error) {       

              trace("Error occurred!");   

       }

}
