The file is created automatically by the plug in the "Temporary Internet

It is the same as opening a pdf file (an URL on a HTML page) from within the

Cool, thanks.
But didn't Bruno say below that: "Most viewer (certainly Adobe Reader)

How are you actually "viewing" the PDF in the browser?
Thanks in advance.
