This is a general question and does not concern any specific problem that I am currently facing.
Since the configuration settings at the child level can override those at the parent level, errors can occur if you have 2 web.config files that override configuration settings that you cannot override, such as authentication or session state. The problem occurs when you have set the authentication / session state on the lower level web.config website, as well as on the higher level web.config.
Are there any other configuration settings like these?
