Problem accessing secure map services

[RahatSyed]

I need to access external secure map services. I have two method to access them i.e. by using REST or SOAP. I am not sure how to access these services. I already generate the token and try to access secure layers by using following:


--------------------REST service Code------------------------------
var url:String = "https://server/rest/services/secure/Utilities/MapServer"
var dynlayer:ArcGISDynamicMapServiceLayer = new ArcGISDynamicMapServiceLayer();
dynlayer.url = url;
dynlayer.token = "yOfJFEixaJa3DDbWHd8njGJdHBknDqKhbBao_w-Ep6Kqne7p6QFJ_4EtaY1Ku1nL";
dynlayer.addEventListener(FaultEvent.FAULT, configFault);
dynlayer.proxyURL = "proxy.ashx";
map.addLayer(dynlayer);
---------------------------------------------------------------

I have been redirected to login page. and got following message:

Can someone help me where I am making mistake?
