I need set the default website application from subfolder, without url rewriting or host headers. I wanna access with www.mydomain.com and not www.mydomain.com/subfolder.
If I understand correctly you want to access this directory www.mydomain.com/subfolder but would like it to come up as www.mydomain.com in the URL address bar?
Yes, also the controllers and url actions, for i.e. www.domain.com/home/about, www.domain.com/car/index, www.domain.com/user/info
