[flexcoders] Detect Application Root

[Angelo Anolin]

Hi FlexCoders,

I have a flex application hosted on an html file.  How would I be able to 
detect 
from the Flex application the root url?

Like for example, the root url goes like:

www.mysite/myApp

and the flex application is hosted on www.mysite/myApp/flex.html

I want to invoke on Flex to navigate back to the root site, www.mysite/myApp, 
but it should be dynamic, regardless which root url it is.

Thanks.
