It's not always possible to get the Application-URL. That's a problem
with other server-side weblanguages too. It's not only the host, but the
path to your application can also differ. My applications only use
relative URL's, to solve this problem. When the URL is really needed
(for example when you send an email to reset a assword) I read the URL
from a xml-file.
