How to Put a website into maintanence/redirect to maintanence page (for changes/updates) in shortest way possible - maintanence page display

Create a file named app_offline.htm. This file can have the content you want to show when your site goes into maintanence mode. You can add nice images and good content to show it to users, whenever your site goes down for maintanence.

You can bring up the site after updates/maintanence by just renaming this file (app_offline.htm) to some other name. Yes, the name is really checked by ASP.net, which internally brings the site down.
