Hi agz29,
Welcome to Bytes.com! I hope you find the site useful.
You've posted your question in the ASP Forum which is for Classic ASP only - I've moved it for you but in future please post all ASP.NET questions in the .NET Forum.
Also, this question could be easily researched first using
Google. I suggest you try taking a look at these first and then coming back with any specific questions that you may have.
