Re: iFrost error - "No Access-Control-Allow-Origin" header is present

CORS is Cross Origin Resource Sharing, and it comes in play here because a
script is trying to do something on a page that originates at a different
origin (your proxy server) than what it is expecting (the vendor's server).

If you proxy the source of the script, then it will be from the same origin
and that usually fixes this error.

In his case I would add

HJ https://ifrost.frost.com

and

MimeFilter application/json .* javascript

to this stanza.
