I want to add services from ArcGIS Server to AGOL, curious on what needs to be done server side to make this happen. Currently my server only allows communication over http and when I try to add a service from server to AGOL (Content -> Add Item -> From a URL), i get the error "Unable to connect, make sure the URL is accessible to the client".
In the hint for the box to enter a URL I see https...so I am guessing AGOL doesn't allow communication over http? This leads me think that I need to enable https on the server.
I want to confirm, is this what needs to be done? In addition to enabling https on the server is there anything else I need to do? I will need to permission to do this so I want to make sure I am asking the right questions doing the right thing before I bother anyone at my organization with it.
One more related question, if I add a service in this manner and update the cache server side; the update will take place on AGOL as well, correct? Because it's just referencing the REST URL.
