Hi,

My colleague has already sent you an answer in a ticket but I will repeat it here also for other visitors.

You need to make also some settings in IIS to use extension-less urls. You can find more details at http://www.kentico.com/docs/devguide/configuration_of_extension_les.htm. Anyway this would cause all urls not to have extension, so instead of that I would recommend creating directory named 'thinkcollege' in root of project folder (in filesystem) and into this directory put default.aspx file that will contain code that will redirect visitor to appropriate 'thinkcollege.aspx' page in CMS.

Best Regards,
Juraj Ondrus
