Password Protection

I have a question on password protection, I went through this one:

http://www.kirupa.com/developer/actionscript/authentication.htm

here on Kirupa which works fine but I need it to go a protected page or a denial page which are both outside of Flash such as an HTML page on my server. Is this possible? I tried to use getURL on the 2nd and 3rd frame with a goto kinda thing but cant get it to work, any suggestions, I am using most of the code off the tute above.

Thanks,
Josh
