Description:I have to deploy some major updates in my website build on asp.net MVC and I can't afford to let my site running during the deployment so I need to setup a page which can be displayed during deployment or the site's down time. preferable I need some settings in web.config or at IIS level so that I can easily remove that maintenance page immediately once the deployment process completed.

The way app_offline.htm works is that you place this file in the root of the application. When ASP.NET sees it, it will shut-down the app-domain for the application (and not restart it for requests) and instead send back the contents of the app_offline.htm file in response to all new dynamic requests for the application. When you are done updating the site, just delete or rename the file and it will come back online.
