I'm looking for an online tutorial on how to setup a client login and registration system on a website. I'm running my own server, hosting my own websites, and I have a MySQL database in which I can store client information. I'm also familiar with ASP.NET and VB.NET. All I need is a basic guide for how to setup certain pages on my website that can only be viewed by clients if they log in (which also means having a login page and a registration page). Any help would be much appreciated.
