Max Concurrent sessions doesn't apply to same browser

i have configured max sessions to be 1 and set error-if-maximum-exceeded=true i noticed two issues:

1- session-authentication-error-url doesn't work if there's authentication-failure-handler-ref configured, the authentication-failure-handler-ref takes precedence and then you will have to handle SessionAuthenticationException there and make needed logic.

2- if i have open session in chrome and try to login in firefox i get the SessionAuthenticationException but if i tried to login again in chrome (which already has an open session) i get login successful and doesn't get the SessionAuthenticationException should i prevent the user from seeing login page if he's already authenticated ? if that's correct, please advise how to do that.

i usually check for authenticated user as follows:

if(!SecurityContextHolder.getContext().getAuthentication().getPrincipal().equals("anonymousUser")){
  // logged in user
}

here's my current configuration:

1- web.xml:

    <filter>
      <filter-name>springSecurityFilterChain</filter-name>
       <filter-class>
            org.springframework.web.filter.DelegatingFilterProxy
       </filter-class>
    </filter>
  <filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
    <dispatcher>FORWARD</dispatcher>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>ERROR</dispatcher>
  </filter-mapping>

  <listener>
      <listener-class>
      org.springframework.security.web.session.HttpSessionEventPublisher
      </listener-class>
  </listener>

2- applicationSecurity.xml:

I personally do it this way.

    @RequestMapping(method=RequestMethod.GET)
    public String login(Authentication authentication)
    {
        if((authentication != null) && authentication.isAuthenticated())
        {
            return "redirect:dashboard";
        }
        return viewResolver.getView(ViewConstants.LOGIN_PAGE);
    }

The method above is used for requesting the login page.

I don't think there is a way to do it using only configuration though. I may be wrong.
