You make another asp.net page and on that page you get this user id and write to the page. from flex app remove this asp.net page with HTTPService and get response. in this answer u get this user id ...



var httpservice:HTTPService=new HTTPService();
     httpservice.url="http://xyz.com/getuser.aspx;
     httpservice.useProxy=false;
     httpservice.method="Post";
     httpservice.resultFormat="text";
     httpservice.addEventListener(FaultEvent.FAULT,GettingException);
     httpservice.addEventListener(ResultEvent.RESULT,Result);
     httpservice.send();


private function GettingException(e:FaultEvent){

 Alert.show(e.fault.message, "Could not load page");

}
 private function Result(e:ResultEvent){

 var Result:String = e.result.toString();
 Alert.show(Result);

}

If you are linking to an ASP.Net page that contains swf, you can obfuscate the user_id and pass it to the querystring, or use a guideline that maps to the user_id. Flex can read a value from a query string. See this article.

Or you can insert the user_id value into flashvars (the ASP.Net page must have access) and read it from there.



userID = Application.application.parameters.user_id;
