web.config中的外部配置节是否已缓存？

Question

I have my own custom configuration section, like this

<configSections>
   <section name="ConnectionStrings"
            type="System.Configuration.AppSettingsSection, System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
            restartOnExternalChanges="false"
            requirePermission="false" />
</configSections>

and I keep it in an external file like this

<ConnectionStrings configSource="connections.config"/>

I know that web.config is cached, and when I change the config, IIS resets the cache and reread the config again after restart...

But In my case, when I change my external config connections.config IIS doesn't restart the app because I set restartOnExternalChanges="false" .

Question: Is my external config cached as well? or IIS reads from it all the time when I use ConfigurationManager.GetSection("ConnectionStrings") ?

Answer 1

Sure, it is cached as well. The API ConfigurationManager.GetSection provides read-only view of the underlying configuration settings.
