Hi Tim, downloading from a browser when posting a form is usually a bit tricky. For me it always ended up with the creation of an artificial <a ...> element with an href crafted from the form parameters and with an attribute download="filename.ext" added to it. Anyway you could try with returning a "forced" application/octet-stream Content-Type header ....

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
