flex：从jsp页面重定向

Question

i am calling a page.jsp from flex application using http, i am checking for authentication on jsp page.now if user is valid than he should redirect to page2.jsp, and if user is invalid user than he should redirect to page3.jsp, i want to redirect from jsp page not from mxml page.

how should i do this?

Answer 1

Forget page.jsp and use a javax.servlet.Filter which is mapped on an url-pattern of /page2.jsp and does the following job in doFilter() method:

if (user is valid) {
    chain.doFilter(request, response); // Just continue request.
} else {
    response.sendRedirect("page3.jsp"); // Redirect to page3.jsp.
}

Then let your Flex app just call page2.jsp .
