Default Referrer and Uri

I just want to confirm that the request coming in to my page is from a certain IP.

If I try this:

Dim foo as String = Request.UrlReferrer.ToString
If Not foo.Equals("999.888.777.666") Then
  ' go to some error page
  Response.Redirect("/foo/bar/noauth.aspx?ErrMsg=" & foo)
  ' or
  ' Responst.Redirect("/foo/bar/noauth.html")
Else
  ' do the rest of my stuff.....

I get a null ref exception, but I can't set the uri to a "new",
why do i have none?

There has to be an easier way than this Uri b.s.

Thanks

The "Uri b.s." that you refer to has nothing to do with your problem. According to the .net documentation UrlReferrer "Gets information about the URL of the client's previous request that linked to the current URL." This is not what you want. It's coming up null most likely because you are typing in the test url directly and thus no referrer is being sent to the server.

What you DO want to look at it is UserHostAddress which "Gets the IP host address of the remote client".
