CORS headers

Hi everyone.

I have a mobile app, which retrieves a link stored in a database. The link resolves to my EmergencyDepartment.App domain. The source is, but the request goes via an Adobe PDF embed script located at

I’m getting a CORS error (never even heard of CORS…) listed below, and have no idea on how to address it…

How can I begin to address this, please?

Thanks so much.
