I was able to make the ParksFinder application work on our external server: http://maps.cityoftulsa.org/Parksfinder/
This is a 10.1 DMZ Server, serving through a 10.1 Web Adapter from a 10.1 ArcGIS Server, using data from a 10.2 Database.
I have setup the app, registered with AGOL, but now I'm getting a weird error.
Failed to load resource: the server responded with a status of 500 (Internal Server Error)
http://<internalserver>.main.cityoftulsa.org/ParksFinder/proxy.ashx?http://server.arcgisonline.com/a...
It does this for all 3 ArcGIS Online services I am using... a couple Topo maps, and an Imagery map.
I can't get the app to move past this section and I'm wondering if it has anything to do with having a registered with AGOL map that is on our INTERNAL_ONLY server... or what?
Confused and lost...
