Use Request.ServerVariables("HTTP_HOST") to get the host part so that you can check if it starts with www. or not.

If it doesn't then just issue a Response.Redirect() to the appropriate URL since it'll do a 302 for you:

e.g.

If Left(Request.ServerVariables("HTTP_HOST"), 4) <> "www." Then
  Dim newUri
  'Build the redirect URI by prepending http://www. to the actual HTTP_HOST
  'and adding in the URL (i.e. the page the user requested)
  newUri = "http://www." & Request.ServerVariables("HTTP_HOST") & Request.ServerVariables("URL")

  'If there were any Querystring arguments pass them through as well
  If Request.ServerVariables("QUERY_STRING") <> "" Then
    newUri = newUri & "?" & Request.ServerVariables("QUERY_STRING")
  End If

  'Finally make the redirect
  Response.Redirect(newUri)
End If

The above does a redirect ensuring the requested page and querystring are preserved

Try this:

Response.Status = "302 Moved Temporary"
Response.AddHeader "Location", "http://www.mywebsite.com/"
