Artemis,
What if you are trying to generate a print that includes secured feature services that are hosted on ArcGIS Online?
We have created an app that is embedded in a website. In order to bypass the need to log in to ArcGIS Online whenever the app is opened, we have utilized the proxy.
We would like to include Esri's print functionality into the app. But with the proxy utilized, the print requests fail as the Esri Print Service does not have permissions to access the layers.
Thanks!
Chris
