Access to values in config, are they cached?

[Bob]

For the appsettings values in .config files, is it cached for very fast
access once a value is accessed? E.g. if I have to call this:
ConfgiurationSettings.AppSettings["MyID"]; on every user action, is it
better off to just store the value in a, say, global static variable?

Thanks

Hi,
appSettings key/value pairs are cached internally; they are not read from
the config file everytime you read them, but just on the first read of any
appsetting param.
