Possibly OT - refreshing page

Hi, I have a page with a link. If the user clicks on the link, the script builds a Word doc using RTF formated data. This is then delivered to the user via a typical header. So far, so good - it works fine. Part of the build process includes a db query which tells the db that the doc for the particular record has been built. I would like the host page to refresh itself once the file has been delivered. I have tried using a popup window to deliver the file but that vanishes once the file has been saved or opened. Any suggestions welcome. Cheers George in Oxford
