What criteria is used to determine if the web.config has changed and needs to be reloaded?
<p>What actions trigger the reloading of the web.config setting? </p>

<p>What does "changed" mean in this context? Does it just compare the modified dates? Do a binary compare? Something else?</p>

<p>Would just opening and closing web.config cause it to be reloaded? </p>
