I've not done this, but if you send the starting page, have that open up
a new tab-page-whatever that handles the download, and then the display
page uses javascript to query the server occasionally (or listens for a
semaphore) to find out when the CSV-sender program has finished, then
the displayed page can trigger the refresh to the completion page.
