ConfigurationSettings vs Application State

[[myfirstname]]

Hello

I've seen several examples around the web where people put all the
values in ConfigurationSettings.AppSettings into Application State
variables in global.asax, like this:

foreach (string key in ConfigurationSettings.AppSettings.Keys) {
Application[key] = ConfigurationSettings.AppSettings[key];
}

Does ASP.NET retreive values from Application faster than from
ConfigurationSettings.AppSettings or what's the point of this?

Just wondering if I should do the same or not...

ConfigurationSettings are cached and Application comes from memory so
basically there isn't so much difference in performance. It's more about the
ability to change the information given to the application.

In .NET v1 configurationsettings in .config files are read-only and more
static by their nature. Application again
could store data without user intervention as the logic requires/does though
people probably use Cache instead of Application because of its better
features from the box. Basically if you want to change configuration yo
don't have to recompile the app, but if you change something in Application
variable, you'd need to recompile the application.
