Help w/ 'headers already sent' and file download

["Mike Walsh" <mike_walsh@xxxxxxxxxxxxxx>]

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.

Thanks,

Mike
