How could I have my website running on IIS return the HTTP Header Code of
503 to the public, and at the same time be able to allow developer to continue developing it locally?
For example, if I use app_offline.htm, it will yield the
503 error to ALL (including the developers), but how could the developer have access and test on it?
Could we make app_offline.htm to be accessible to only a group a people? Or is there any other alternatives to have
503 and local development happen at the same time?
