Is there any possibility where I check what was my last page visited. I have a requirement like this to handle refresh event in flex pages. when I refresh my page I want to go back to same page your valuable comments and your knowledge is needed.

public function initSharedObject(userAgent:String):String
    {
        Alert.show("userAgent : "+userAgent+" substring : "+userAgent.substr(0,15));
        sharedObj = SharedObject.getLocal("SO_"+userAgent.substr(0,15));
        if (sharedObj.size > 0)
            var currentState:String =sharedObj.data.tasks;
        //Alert.show("curentState in init "+currentState);
        return currentState;
    }

    public function saveTasks(curentState:String):void {
        //Alert.show("curentState  "+curentState);
        sharedObj.data.tasks = curentState;
        sharedObj.flush();
    }

    public function deleteSavedTasks(userAgent:String):void {
        //Alert.show("Im in Delete ...");
        //Alert.show("userAgent : "+userAgent+" substring : "+userAgent.substr(0,11));
        sharedObj = SharedObject.getLocal("SO_"+userAgent.substr(0,15));
        sharedObj.clear();
    }

Hi Adrain , above code I am using in the share Objects handling in my application,But Sub String of userAgent String give me Output :

IE 11 : userAgent : Mozilla/5.0 (Windows NT 6.1; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E; InfoPath.3; MS-RTC LM 8; rv:11.0) like Gecko substring : Mozilla/5.0

Mozilla : userAgent : Mozilla/5.0 (Windows NT 6.1; rv:27.0) Gecko/20100101 Firefox/27.0 substring : Mozilla/5.0

Please check the above code and its substring output. and please let me know.

Why not to create a NavigationManager class where you can store in static variables the informations you need.

For example

class MyNavigationManager
{

    private static var _visitedPages:Array = [];

    public static function pushPage(pageName:String):void
    {
        _visitedPages.push(pageName);
    }

    public static function get currentPageName():String
    {
        if(_visitedPages.length > 0 )
             return _visitedPages[_visitedPages.length -1 ];

        return null;
    }

    // ...something else you may need, maybe popPage():Sting...
}

And to use it you can call from any place in your app 

MyNavigationManager.pushPage("Home");
MyNavigationManager.pushPage("User Account");
trace(MyNavigationManager.currentPageName);

Update 1

Since you need independent SharedObjects based on browser type (as requested in the comments...)

Get browser name

var userAgent : String  = String(ExternalInterface.call("function(){return navigator.userAgent}"));
trace (userAgent);

Use userAgent to create different shared objects, and initialize like this.

public var sharedObj:SharedObject;

private function initSharedObject():void
{
    sharedObj = SharedObject.getLocal("SO_"+userAgent.subStr(0,6));
}

Hope that it is better now.
