Java Spring Session not persist between requests

I have this controller

@Controller
@RequestMapping(value = "/login")
public class Login{

    @RequestMapping
    public ModelAndView mainPage(HttpServletRequest request){

        request.getSession().setAttribute("testSession", "Session test");

        return new ModelAndView("/login");

    }

    @RequestMapping(value = "/check")
    public View check(HttpServletRequest request){

        System.out.println(request.getSession(false)); //null

        return new RedirectView("/login");

    }

}

When access /login I create a session and add an attribute "testSession" into it: request.getSession().setAttribute("testSession", "Session test");

On page /login have this <form action="/login/check" method="post">.

On /login/check I try to get session created on /login, but it is null.

Why session not persist between requests?

P.S.: My app run on Remote Server with Tomcat and Apache as revers proxy and I access my app via https://mydom.com

UPDATE

I created a controller to test session:

@Controller
@RequestMapping(value = "/sess")
public class TestSession{

    @RequestMapping(method = RequestMethod.GET)
    public void mainPage(HttpServletRequest request, HttpServletResponse response) throws IOException{

        //get or create session
        HttpSession session = request.getSession();

        response.setContentType("text/html");
        response.getWriter().println(session.getId());

    }

}

At every request to /sess it's printed another id.

The real problem was at JSessionID path.

The path of JSessionID was /myapp. That was result of Tomcat, because my app normaly run under mydom.com:8080/myapp

But with Apache as reverse proxy, I run my app directly from mydom.com/, which make JSessionID invalid because I'm not on mydom.com/myapp.

So I added a new line in virtual host from Apache(where is setted reverse proxy) to change the path of cookies:

ProxyPassReverseCookiePath /myapp /

This is my final VirtualHost and now Session persist between requests.

<VirtualHost *:80>

    ServerName mydom.com

    ProxyRequests Off
    ProxyPreserveHost On
    ProxyPass / http://127.0.0.1:8080/myapp/
    ProxyPassReverse / http://127.0.0.1:8080/myapp/
    ProxyPassReverseCookiePath /myapp /

</VirtualHost>

Are you using spring security? May be you can set http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.NEVER) if you are managing sessions by yourself
