I am the owner/developer of these websites. Before I upload them to my hosting provider, I test them locally using IIS.
Convert them is no option, when scripting/developing something things can be done in different ways, I could have used PHP at that time, or ASP.NET, or Ruby, or any other thechnology, but I have used ASP and will continue to use ASP for those.
Also converting is no option because we are talking about thousends of pages scripting code, believe me lots!
I know what I am asking is possible, because different people has told me that, but don't know how to do that.
So the problem still remains.
Already thanks for the answes
