Hello This thing is really frustrating me.I have to admit i dont understand cross origin requests well. Here is my code:

javascript :

var config = {

            headers: {

                'Access-Control-Allow-Origin' : '*',
                'Access-Control-Allow-Methods': 'POST, GET, OPTIONS',
                'X-Parse-Application-Id' : 'xxxx',
                'dataType' :'json',
                'Content-Type' : 'application/json'

            }
      }



    $http.post(link,data_model,config).
      then(function(response) {

        deffered.resolve(response);
      }, function(response) {

        deffered.reject(response)
      });
      return deffered.promise;
  };

This is how i set headers as i post to the server. I am posting to a page called utility.php.

in utility.php i have the following headers;

<?php
    /**
     * End point utility class
     * 
     *
     * @author Tariiq Henry Bbosa
     */
    header('Access-Control-Allow-Origin: *');

    header('Access-Control-Allow-Methods: POST, GET, OPTIONS');

When i try to make my post request i get this error:

XMLHttpRequest cannot load http://localhost:89//fotoserver/utility.php. Request header field Access-Control-Allow-Origin is not allowed by Access-Control-Allow-Headers in preflight response.

Someone please tell me which header i should include where. So that myy request can go through. Please dnt refer me to a big page to read. Just help me out here.I will read after.

To resolve CORS issue, server should send 'Access-Control-Allow-Origin' : '*',... in its response headers.

If a client is running on a different domain than the server, browser blocks request for security. If server allows Cross-Origin requests, browser won't complain.

So instead of putting the headers in client $http.post() request, put the headers in response of utility.php

During the preflight request, you should see the following two headers: Access-Control-Request-Method and Access-Control-Request-Headers. These request headers are asking the server for permissions to make the actual request. Your preflight response needs to acknowledge these headers in order for the actual request to work.
