Response for preflight has invalid HTTP status code 403
<p>I am using as Server-side Spring-boot and providing a dummy service for test</p>

<p>where my <strong>ServiceCaller.java</strong>=</p>

<pre><code>package com.user.server.mfw;

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;

import javax.servlet.ServletException;

    private void checkActiveSessionControl(HttpSession session)
    {   
        System.out.println("Session Id:" +  session.getId() +" // " + session.getCreationTime());
        if(session == null)

        else
            System.out.println("Old");
    }



}

<p>where my client-side is a ionic framework and based on angular.js...</p>

<p><strong>Controller.js</strong></p>

<pre><code>   $scope.getInfo = function() {
    $http({
        url: SERVER_ENDPOINT.url + '/serviceCaller',
        method: 'POST',
        params: {serviceName: 'deneme'},
        withCredentials: true
    }).then(function(result) {
      var alertPopup = $ionicPopup.alert({
        title: 'ALOHA!',
        template: 'dksjd ' + result
      });
      $scope.memberInfo = result.data.accountNumber;
    }, function() {
        var alertPopup = $ionicPopup.alert({
          title: ' failed!',
          template: 'da'
        });
      }

    );
  };
</code></pre>

<p>Basically I get a "invalid HTTP status code 403" when I use POST method instead of GET. However I would like to use <strong>POST</strong> for calling instead of <strong>GET</strong>. 
However I could not figure out where I am making a mistake.... </p>

<p>any solution will be appreciated! </p>
