multiple .net applications, single point to put sites in maintenance mode
<p>I have a asp.net website that has other 'child' asp.net applications within that are setup as separate IIS applications, while others are not child applications.</p>

<p>What would be a good way to prevent users from accessing the website during deployments/updates/downtime.</p>

<p>I know I could do this using the web.config, but that would mean me having to update multiple web.config's manually during site lock downs.</p>

<p>I could also have each request hit the database, but that seems a little much for this.</p>

<p>Suggestions?</p>

<p>I don't have direct access to the servers so I can't fiddle with IIS.</p>
