HttpServletResponse Output

[Eduardo Bueno]

 response.setContentType("application/vnd.ms-excel");
                response.addHeader("Content-Disposition",
                        "attachment; filename=someFile.xls");
                response.getOutputStream().write(someByteArrayOutputStream.toByteArray());
                response.getOutputStream().flush();   

This code works fine. The application creates a xls file that is flushed by the response object to the client.

My doubt is: who manages that response? Is it the browser, the client's OS or the client's JVM who opens the window with open/save/cancel options?

The browser. The client JVM will not be running unless there is an applet on the page.
