Hello All, We have developed the Routing application using ArcGIS Flex and we have deployed on IIS server with ASP.Net application and when in flex if we reference the ArcGIS Server services by IP Address then it's working perfect but when we make the ArcGIS Server rest service available in public i mean to say when we access like this http://domain/ArcGIS/rest/services it's giving Security Sandbox Violation error, i did make sure that we have crossdomain file on the server.
