I am creating my own Token via aspx .net login page. I am setting the Expiration of this Token as well.
Once authenticated the user is passed to an aspx page leveraging JavaScript API in a .js page to render the layers and map
It is here I am adding the Token to the Map Service: see below
var Data = "https://myserver.gov/arcgis/rest/services/Test/blers/MapServer?token=";
Data += MapServerToken;
map.addLayer(new ArcGISDynamicMapServiceLayer(Data,
{ opacity: .8 }));
If the app stands idle for an extended period of time the Token will expire.
Is there a way to test whether a Token is still valid or not via JavaScript?
If this is possible I would like to then redirect them back to a login page.
Anyone? Thanks in advance
