I am developing a servlet, which will send user a file and also a successful page by clicking on a single button on a page.

I have no problem with sending user a file...... but i don't know why I could never send the successful page across, there is no error and it seems the browser just ignore the successful page........ Here is my questions.

1. Does http allows 2 responses for a single request?
2. Can I send 2 responses with the same response object?

Thanks for any help.

No and no.

If you'd give further details of the scenario, we can make some suggestions.

I have a page and in it I have a button "Export" for the user to click on, when they want a soft copy of their details (a plain txt file with all the user details). And then show a message " export successfully " on the window.

HttpServletRequest req = context.getRequest();
HttpServletResponse res = context.getResponse();

res = context.getResponse();
res.setHeader("Content-disposition","attachment; filename=user.txt");
ServletOutputStream out = res.getOutputStream();

res2 = context.getResponse();
// return the successful page here
