title: XMLHttpRequest cannot load, No 'Access-Control-Allow-Origin' header is present (Unable to read Ajax response in JavaScript/jQuery )
body: <p>I'm sending an Ajax request to server using jQuery, below is the code snippet.</p>
  
  <pre><code>$.ajax({                
                  type: 'POST',
                  url: "https://store.example.com/account?",                
                  data: "cf=cw&amp;operation=update"
              })
  </code></pre>
  
  <p>Definitely, “requested page” and “Ajax request’s URL” are in same domain. Still, Am seeing specified error message in browser console and unable read response with JavaScript/jQuery. Please help me here.</p>

    <p>Error message:              XMLHttpRequest cannot load
    <a href="https://store.example.com/account" rel="nofollow">https://store.example.com/account</a>?. No 'Access-Control-Allow-Origin'
    header is present on the requested resource. Origin
    '<a href="http://store.example.com" rel="nofollow">http://store.example.com</a>' is therefore not allowed access.</p>
