Every once in a while you need to restart Alfresco. When you do, it would be nice if the user could be informed on why the system isn’t available.
For this purpose I have created a maintenance page to be used when you use Nginx as a front-end to Alfresco. It will detect when the backend (Alfresco tomcat instance) is not available (you get an 50x response) and instead display this page:
