Help w/ 'headers already sent' and file download

I have an application which I am working on which takes a file supplied by the user via a File Upload, peforms some processing on it, then prompts the user to download a generated CSV file. What I would like to do is report some processing statistics prior to the user prior to sending the CSV steam. My CSV export ends with this: header("Content-type: application/vnd.ms-excel") ; header("Content-disposition: attachment; filename=CSVData." . date("Y-m-d").".csv") ; print $csvStream ; Unfortunately if I display any content prior to sending the CSV stream I get the 'headers already sent' error message. Is there a way to both display a web page and send content to be saved by the user? If someone knows of an example I could look at I'd be greatful.
