The server won&#x27;t send the Content-Disposition:&quot;attachment[...]&quot; header if you use this URL: <a href="http:&#x2F;&#x2F;ojs.stanford.edu&#x2F;ojs&#x2F;index.php&#x2F;intersect&#x2F;article&#x2F;viewFile&#x2F;703&#x2F;617" rel="nofollow">http:&#x2F;&#x2F;ojs.stanford.edu&#x2F;ojs&#x2F;index.php&#x2F;intersect&#x2F;article&#x2F;view...</a>.  (For me, the abstract page was confusing, because you have to see the tiny &quot;PDF&quot; link and then click it to get to the actual article.)
