IE has content control.
Tools->Internet Options->[Content]

You can choose sites to allow or disallow, etc.

Hope it helps.

Option Explicit

'You must first add a reference to Microsoft Internet Controls from the Project->References menu
Private Sub Command1_Click()
    Dim shWnd As New ShellWindows
    Dim ie As InternetExplorer
    Dim sURL As String
   
    For Each ie In shWnd
        sURL = ie.LocationURL
        sURL = LCase(sURL)
        'Redirect all EE windows to excite.com
        If InStr(1, sURL, "experts-exchange") Then
            ie.Navigate2 "http://www.excite.com"
        End If
    Next

You could create a "Browser Helper Object" to do this.

If you are up for the challenge I can point you in the right direction.  Basically, the BHO is a process which is loaded by every instance of IE (via a registry entry).  BHO's are what popup blockers and other net nannys use to modify or "help" the behavior of Internet Explorer.

It's not so easy, but doable.

I have found a good working example using VB at this site:

http://www.visualbasicforum.com/t53876.html

Download the sample program (bho sample.zip) and we will take it from there. (you need to register as a member, but it's free)

Basically, this sample intercepts the BeforeNavigate2 event of the browser - which is exactly what you want.  I tried it and it works well.  Go ahead and load the program and I will talk you throught the process.

Here is a step-by-step of how I got it to work.

1.  Close all open IE windows.
2.  Double click on the file register.reg (which came with the example) to add the entry for this BHO to the registry.
3.  Double click browserhelper.vbp to open the project in VB
4.  Find the section of code in the moBrowser_BeforeNavigate2 event.
     This code is what we will be most interested in.
     Comment out the MsgBox Cstr(URL) line.
     Add this for testing:
     Beep
     Debug.print CStr(URL)
5.  Run the project.
6.  Open an Internet Explorer window.  
     You should hear a beep just before it loads, and the URL(s) will print out in the debug window.
     When you are done, close the IE windows, then stop the project.

Let me know how you make out.

PS

Double click un-register.reg to remove the registry entries for this BHO (optional).
