React/Redux store state is not saved

Question

I use thunk middleware and pass initial state to React, but the problem is that React state is not saved when I visit other links.
After successfully logged in, it's supposed to render dashboard.
User must be redirected to dashboard(which is the root path, /) when he tries to go to /login page.

Should i use redux-router too?

I omitted some of code, but it almost looks like below.

init.js
I passed store to Provider

import { Provider } from 'react-redux';
import configureStore from './store/configureStore';

const store = configureStore();

function requireAuth(nextState, replace) {
  const isLoggedIn = store.getState().auth.isLoggedIn;
  if (!isLoggedIn) {
    replace({
      pathname: '/login',
      state: { nextPathname: nextState.location.pathname }
    });
  }
}

<Provider store={store}>
    <Router history={browserHistory}>
      <Route path='/' component={App} store={store}>
        <IndexRoute
          components={{
            main: MainServices,
            aside: Aside
          }}
          onEnter={requireAuth}
          />
        <Route
          path="login"
          components={{
            login: Login
          }}
          />
         ...
    </Router>
  </Provider>

configureStore.js

import { createStore, applyMiddleware } from 'redux';
import thunk from 'redux-thunk';
import rootReducer from '../reducers/index';
import initialState from './initialState';

const store = applyMiddleware(thunk)(createStore);

export default function () {
  return store(rootReducer, initialState);
}

initialState.js

var initialState = {
  auth: {
    isLoggedIn: false,
    isLoggingIn: false,
    response: null,
  },
};

export default initialState;

App.jsx Initial App's state passed down to React's props

import React, { PropTypes } from 'react';
import { connect } from 'react-redux';
import Dashboard from './Dashboard';
import Login from './Login';
import { browserHistory } from 'react-router';

class App extends React.Component {
  constructor(props) {
    super(props);
  }

  render() {
    return (
      <div className='appWrapper height'>
        {
          this.props.auth.isLoggedIn ?
          <Dashboard {...this.props} /> : <Login {...this.props} />
        }
      </div>
    );
  }
}


let mapStateToProps = function(appState) {
  return {
    auth: appState.auth,
  };
};

let mapDispatchToProps = function(dispatch) {
  return {
    logoutRequest: function() {
      console.log("logoutRequest dispatched!");
    }
  }
};

export default connect(mapStateToProps, mapDispatchToProps)(App);

Login.jsx

export default class Login extends React.Component {
  constructor(props) {
    super(props);
    console.log(`componentWillMount in login`);
    if (this.props.auth.isLoggedIn) {
      console.log(`you already logged in..!`);
      browserHistory.push('/');
    }
  }
  render() {
    return (
      <div className="login-outer">
        <Grid className="login-inner">
          <Row>
            <Col xs={12}>
              <LoginHeader />
              <LoginContainer />
            </Col>
          </Row>
        </Grid>
      </div>
    );
  }
}

LoginContainer.jsx

export default class LoginContainer extends React.Component {
  render() {
    return (
      <div className="login-container">
        <div className="outer">
          <div className="inner">
            <LoginTitle />
            <div className="login-box">

        </div>

    );

There is no way how your store can be saved between two different http requests. The only approach for that is not reloading page itself, but you can emulate for user that page was reloaded when user clicks the link by manipulation with history API which is native object in all modern browsers. BUT best approach is to take react-router which will take care about everything you need in your react App, and if you want to keep state of the router in your redux store you can use redux-simple-router.
