We're attempting to implement use of the PDF api for our external site, but we're finding that many of our clients have firewalls that are blocking the documentcloud.adobe.com since it's basically a file upload site. The product Zscaler actually blocks it by default. This has the result of blocking the necessary include files. We can whitelist it for ourselves, but not for the general public or our many clients. We've tried a reverse proxy, but that also didn't work all that well. Is there any chance to move these js files to somewhere that's not under a commonly blocked subdomain?
