Quickly Taking an ASP.NET App Offline Temporarily

asp.net

If you need to quickly take down an ASP.NET app for maintenance, you can simply place an HTML file called "app_offline.htm" in the app’s root directory. Whatever HTML you have inside that file will display instead of the normal app. Here’s a quick template you can use for your file:

<!DOCTYPE html>
 <html>
  <head>
     <style>
        body {
           text-align: center;
           font-family: sans-serif;
        }
     </style>
  </head>
  <body>
     <h1>We'll be back shortly</h1>
     <p>We're sorry, this site is temporarily down for maintenance but will be back up as soon as possible.</p>
  </body>
</html>
