Use IIS under VS 2008, rather than the development server, Casini
Set up a new application in IIS, point it to the root of your project, and check that it works, by going to a browser, and type localhost/myApp
Then right click your web applicaiton in Visual Studio, select "Property Pages", then "Start Option", set Start URL to localhost/myApp,
check "Use custom webserver", then base URL to "http://localhost/SellSwapBuy".
When you run your app now, you can still debug, but it will be under IIS not Casini.
