Saving a page/text file from a query

Hello all, I need to display a page on text format that will be the result of a query. This page will not be saved on my server harddrive but it has to allow the user to save it to their HD. The problem is that the page has to be saved on the customer HD automaticaly (He/She should not click on the browser's save option) and it also has to be saved on a fixed file name like text.txt or schedule.csv. Does anyone know how to implement that? Thank you very much, Carlos Fernando Scheidecker Antunes.
