To make it easier for users to get to a section of our site, we created a virtual directory alias which redirects the user to a specific web page. If there's no virtual directory for http://www.mysite.com/subdirectory/webpage.aspx, then that Master Page reference works fine. But once I created a virtual directory and attempted to get to that same page by typing the path to the virtual directory (http://www.mysite.com/subdirectory), I received this error message relating to the web page trying to access our site's Master Page, which is located in the root of the site:
Server Error in '/subdirectory' Application.
