The Auto Heal setting

The Auto Heal setting can allow your web site to perform an administrative action if certain conditions are raised.
 
The triggers are:
  • Memory usage
  • An HTTP status code
  • HTTP request count
  • Slow requests
 
The actions that can be performed are:
  • The application pool for the web site can be recycled
  • The event can be logged
  • A custom action can be performed
 
For example, if your web application reaches 750 MB of memory usage, the application pool can be configured to automatically recycle.
