How does ConfigurationManager.AppSettings.Set stores values?

Hello everybody,
you can use ConfigurationManager.AppSettings.Set method
(ConfigurationManager is in System.Web.Configuration namespace) to store a
modified value from web.config.
To be practical, you define a custom key in web.config:

<appSettings>
<add key="ReportButtonClick" value="0" />
</appSettings>

retrieve value of the key with Get method:

counter = ConfigurationManager.AppSettings.Get("ReportButton Click")

modify this value:

counter = counter + 1

and write it back with Set method:

ConfigurationManager.AppSettings.Set("ReportButton Click", counter)

If I access back value with Get method, I find modified value but, of
course, web.config is NOT modified.
Where does Set method stores property's value?

Cache

Good answer, Terry, but I'm not so comfortable about caching in ASP.NET
How do examine cache for my application?
And, is using cache scalable to million of users?

P.S.: a little question: I'd like to download newsgroup in OE. What is NNTP
Server? Does it require authentication? If so, do I have and type my Passport
credentials?

No, it does not.
