Introduction
I've been doing this trick for a while now and thought it was worth sharing. The problem is when you rely on cookie values in a web-app, in order to reset these values, you need to remove the cookies manually (or in code) on app start. Not ideal. The solution to this minor annoyance is to set up specific browser sessions that use the "PRIVATE BROWSING" command line parameters of browsers. What happens is when you start a private browsing session, it does not use any cached cookies or other settings so you can test with a clean slate - handy.
Setting It Up
In Visual Studio, select the drop-down arrow to the right of the browser choice window:
Now select "browse with"...
In the dialog that pops up, select "add", and use the "..." button to locate your browser. In Arguments, enter the "in private" command line argument your chosen browser takes.
For chrome, use "-incognito", for Internet Explorer, use "-private". The documented "-private" for Firefox does not seem to work.
Your new run with browser menu should now show the new options:
When you run/debug, you get your new shiney cookie free window!
Enjoy your low-fat "cookie cache free" testing!
