Is there a way for an ASP.NET app to show a wait screen to the user that kicks off the Application_Start event?
<p>Greetings folks,</p>

<p>The ASP.NET application I'm maintaining has a fairly long start up procedure.  A number of data files are updated, etc.  I've been asked if there is a way for the application to return a wait screen (static if necessary) while Application_Start is running?</p>
