how to stop progress indicator after downloading a pdf

There is a link on my page to a pdf file. Clicking on the link takes a really long time, so I'd like to throw up a progress indicator gif showing that it is something that takes a while. But how do you hide the indicator once the pdf has been generated on the server side and finished downloading? (basically your browser now says you are opening a pdf file and asks you what to do)

at this point is there an event that fires or anything I can poll to check to hide the progress indicator?

JavaScript does not have access to information on what's being downloaded. The only thing you can do is load the PDF in a Iframe and hook up the onload event on the Iframe. Even then the event will fire when the PDF starts loading, not when it is complete.

EDIT: kalendae has alternate answer.

If you have server-side access you can set a cookie with the response and poll for its value on the client.
