For the most part, it'll work the way you're doing it. My point was about
the degree to which you could guarantee that info being correct. Any
information provided by the browser can be tampered with. For example, if
your app is looking at HTTP_HOST or SERVER_NAME to see whether the user can
access an administrative interface, I can write a script which says it's
looking for "localhost" or whatever your app is using. If that's not a
concern to you, then don't worry about it.
As an alternative, what I generally recommend for machine-specific
application settings is that you store them on the machine itself, and have
your application read those values from wherever you've stored them. You
could store them in a text file, or within the registry, for example. If you
store them in a file, make sure that file doesn't get overwritten when you
move a new build of your application from development to production.
