Question

How to return from navigateToURL() call?

I'm relatively new to Flex 4 and AS3, so if this question seems stupid, that's not intentional; it's a function of my learning...

The Question: How can one navigate from a Flex 4 / AS3 application to a URL not directly related to it, and then return to the Flex 4 / AS3 application in the same state it was when it was "navigated away from"?

I'm working on an application to which users are authenticated via a web single signon ("WSSO") application external to mine. Access to my application's initial page is granted by successful authentication in the WSSO tool. This authentication is effected through a web page hosted on the servers managing access to resources.

The WSSO application allows access for some period of time before the authentication it granted times out, and requires re-authentication before access to any protected resources is again allowed.

A timeout is detected whenever a call to one of the HTTPServices protected by WSSO returns a FaultEvent containing the HTML of the WSSO login page as its message. I can navigate to the URL corresponding to that HTML, requiring the user to re-authenticate, but how do I get "back" to the Flex application?

you can use the localconnection class to communicate between two windows open at the same time on the same computer.

kglad, appreciate your response. I don't have any control over the WSSO page. The results of successful re-authentication are simply that HTTPService requests to protected resources complete normally, rather than being returned as FaultEvents. Conceptually, I'd like to direct the user to the WSSO authentication page when a timeout is detected, and, once they've been (re-)authenticated, return back to the Flex application in the state it was in at the time the authentication interruption was detected. From what I read about the LocalConnection class, that doesn't seem to address this...

you can't use localconnection.

and, i don't think you're going to be able to use navigateToURL the way you currently are. 

you'll need to use javascript to open the authentication page and use javascript/cookies to communicate between the two open windows.

you can use the externalinterface class to most reliably communicate between flash and javascript.
