Try to add response header
Content-Disposition: attachment; filename="filename.pdf"
Thus, the document begins to download, it is necessary that he first went on the preview - Willa.Smith36 commented on June 10th 19 at 17:03
try Content-Disposition: inline; filename="foo.pdf" - ale commented on June 10th 19 at 17:06
