The correct type is application/pdf for PDF, not application/force-download. This looks like a hack for some legacy browsers. Always use the correct mimetype if you can.

If you have control over the server code:

• Forced download/prompt: use header("Content-Disposition", "attachment; filename=myfilename.myextension");
• Browser tries to open it: use header("Content-Disposition", "inline; filename=myfilename.myextension");

No control over the server code:

• Use the HTML5 download attribute. It uses the custom filename specified on the view side.

NOTE: I prefer setting the filename on the server side as you may have more information and can use common code.
