If you're like me, then you build large ASP.Net applications that have a Login page the user must pass through before being able to do anything else. I use a lot of template code so I don't have to reinvent the wheel each time. Part of this code redirects unauthorized users back the Login page. This means that to perform the Run-Debug cycle the developer has to login each time and then go the page they're working on. Not a big deal but tedious and, I've discovered, unnecessary.
I've added a little code to my projects that allows an AutoLogin and Redirect to the desired Start Page. I've written about it here: http://mwtech.blogspot.com/2009/08/developer-autologin-redirect.html
Hope it helps others too!
