I want flex application to check when it loads weather user is already authenticated or not .

You can use shared objects, the Flash version of a cookie. Also, if you're using server side sessions, reloading the page should not reset the browser cookie which ties your front end to the back end session. So, you could always ping the server to see if the user authenticated there.
