I have a web app that I am deploying using AEM. The app uses a library, which makes HTTP GET requests to the localhost. These calls are being rejected. Cordova only handles file:// protocol requests and I assume that AEM is doing something similar although it is difficult to check because I can't debug the web app when it is running within the AEM Preflight app. There is a workaround in Cordova. Might there be something similar in AEM?
