Quite impossible. You know as well as I do that the Acrobat plugin is an ActiveX control located on the client. From the server you have no control over it. If the control itself doesn't provide the functionality (and it doesn't) there's little you can do.

What if I send it not as pdf file, but as byte stream? or any other way? can't believe it's impossible
How long does this PDF load take anyway? I suppose you could do some complex combination of an applet that talks to the server and gets information about how much of the pdf remains to be sent, but would it really be worth the trouble? Bill
