I don't know how you have it set up, but I can give you some info and give you an idea of where to look for more info. ASP.net controls login information with either session state or with cookies. Depending on how you've set it up it creates a cookie file or puts the login information in the URL. If you are using logins you should be encrypting them as well and asp.net can handle that for you as well. I recommend highly that you check out a book called Murach's ASP.NET 2.0 Web Programming with VB 2005 ISBN#1890774324





This book compartmentalizes everything and is very complete and professional. It has a complete section that shows you how to do cookies, session state, and encrypt login information.
