Another way is to use a session variable that is passed only from certain pages…You can do such a think by instantiating the variable in an onclick event on the server side. The coding is pretty simple, it’s just:

VB.NET:
Session(“mySession”) = myValue

C#
Session["mySession"]=myValue;

Then, you can set up an if block to check on the page load event if the session variable exists and is set properly. If not, redirect the user. I’ve used a simply boolean value assigned to a session variable to set whether the user can access a page or not before.

If you only want certain machines to be able to access the stated pages, you can do something like:

Dim s
s = Request.ServerVariables (“REMOTE_ADDR”)

‘ if not acceptable addresses then redirect
if s <> “127.0.0.1″ and s <> “127.0.0.2″ then
Response.Redirect “Your URL”

end if
