Hello,

I am posting a JSON doc to a RESTXQ function from XForms and trying to set a Content-Disposition header to trigger a file download. Is this possible to do without first saving the JSON doc as a file? Right now, the RESTXQ function returns the correct headers, but does not force a file download dialog.

Thanks in advance!

Tim
