I have a content management application in the root of my website, and I\'m trying to use a different app (a billing application) under a sub-folder. Unfortunately, the web.
In my opinion every time I've struggled with this the answer ends up being effectively NO - and I'm leaving this here for my future self to find so he doesn't waste any more time on it.
I've found this to be a huge problem when you just want to add something as a virtual directory inside an existing site. With a complex web.config files I've always just ended up giving up and moving it to a different application altogether.
