how to detect re-directs using loadURL

[RGould8 at aol.com]

Can anyone tell me if it's possible to detect whether an URL is being  
re-directed, using load URL or some other command?
 
I'd like to see if there's a way I can get the following status from a  
server when loading an URL, but I'm not sure how to retrieve it:
 
302 Success: Found Redirected to: (url)
200 Success: OK
301 Success: Moved Permanently

Can anyone point me in the right direction?
