Overriding isSystemOn setting for a single page I have a staging site that has the isSystemOn set to false since I don't want people to stumble upon the site and be able to view content. I would like to have 1 page still "visible" though. This URL would a simple health check page, that I direct a monitoring service to check on. I'm stumped at overriding a system level isSystemOn config setting. 

Can I have staging.example.com/my-secret-health-check-url return a valid code of 200 so my monitoring service can correctly see that my staging site is working?
I realized there is a simpler solution after stepping away from this issue for a bit. There is one page that still returns a 200 code on a Craft site even when the isSystemOn (or isSystemLive as of Craft 3.1) is false. Using the control panel login page as a health check url is the solution.
