Response.Redirect should be used when:

1. Redirect the request to some plain HTML pages on our server or to some other web server
   
   
2. Don't care about causing additional roundtrips to the server on each request
   
   
3. Do not need to preserve Query String and Form Variables from the original request
   
   
4. Users to be able to see the new redirected URL where he is redirected in his browser
