I am using Windows Server 2003 + VSTS 2008 + .Net 3.5 + C# + ASP.Net + IIS 6.0. I host some files (wmv video file and html file) on the web server, I want to know whether there are any easy to use authentication approach to let user input username and password before they can access (I want to prevent anonymous access)? Since the web site has also aspx ASP.Net page, and I want to use an unified authentication solution for wmv, html and aspx page. If prefer any solution which utilizes username and password stored in SQL Server database which my application already has/use.
there is a shopping cart issue what I am working on right now. I am adding a back button, but for posting back to the server, the required fields need to be validated. Is there a way how I can skip the validation for the back button?
