Servlet won't redirect me

Question

i have logout button and when its pressed i want to return to main page but it stays on current page. although i receive response in chrome developer tools.

userinfo.jsp

<input type="button" onclick="logout()" value="Logout" class="btn" style="margin-top: 10px; margin-bottom: 10px;"/>

logout.js

function logout(){

    $.post("Logout");

}

Logout.java servlet

public class Logout extends HttpServlet {
    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        PrintWriter out = null;

        try{


            HttpSession sess = request.getSession();
            if(sess != null){

            sess.invalidate();

            }

            response.sendRedirect("index.html");

Here's Response

I do not know jquery so well but I think that this call is responsible for behavior. Can you test normal form without javascript? — Leos Literak, May 01 '14 at 11:01
`$.post("Logout");` is an ajax call. Why would the page redirect? — Subir Kumar Sao, May 01 '14 at 11:03
solved it. i used windows.location instead of ajax call. thanx @Subir Kumar Sao — user2513301, May 01 '14 at 11:15
If you redirect inside a servlet being hit by Ajax, that does not redirect the page that sent the Ajax request. It redirects the Ajax response only. And you aren't even reading the response to the Ajax request! — developerwjk, May 01 '14 at 17:39

Use RequestDispatcher instead of using sendRedirect

For Example:

RequestDispatcher reqDispatcher = req.getRequestDispatcher("pathToResource/MyPage.jsp");
reqDispatcher.forward(req,res);

Read why and when to use each of RequestDispatcher and sendRedirect

How is this an answer if the OP wants to redirect? – Koray Tugay May 01 '14 at 11:18
i also used dispatcher instead of redirect – user2513301 May 01 '14 at 11:20
I agree, the problem was in client side, this answer is irrelevant to the question. – Leos Literak May 01 '14 at 11:20

<input type="button" onclick="window.location.href='/path/servlet.java'" value="Logout" class="btn" style="margin-top: 10px; margin-bottom: 10px;"/>
