I'm looking for some basic information on configuring the proxy. Following is a description of our setup:
Secured map hosted on ArcGIS Online
A customization of the GeoForm template hosted within IIS that uses the secured map on ArcGIS Online
A link to the externally hosted application in ArcGIS Online.
Currently, the user has to log in to ArcGIS Online each time they access the application (even as they're already signed into ArcGIS Online).
