New Issues with FDF Loading PDF from Intranet Zone
Adobe Acrobat Reader DC 2019.010.20064 has apparently broken the Adobe FDF Loading of Form Field data from an intranet server configured with the Adobe PDF Toolkit while using Internet Explorer 11. Now instead of as before where the Classic .ASP page would load the form fields and then load the target PDF file multiple tabs open. The first tab shows only an "Initializing..." message from Adobe while the second tab is the PDF file without any of the FDF field data loaded.
The code on the intranet has not been altered and has ran for numerous years without issues with the clients using their "Automatically trust sites fro my Win OS security zones" and even the "Add Host" options of the specific intranet server.
The Classic .ASP page does set the MIME Type as below:
Response.ContentType = "application/vnd.fdf;charset=UTF-8"
This was not an issue till recent updates. Digging around the web there appear to have been similar issued in Adobe Reader versions in the past that were considered BUGS and then resolved in updates.
