If you have a large number of AppSettings items, you could create a
second file (name it myAppSettings or whatever), listing all your
appsettings there, and in your web.config file, just refer to that
other file
<appSettings configSource="myAppSettings.config"/>

This way, also, if you make an addition to the myappsetings file, it
won't restart the entire application.
