title: Load Html Content if not exist JQuery AJAX
body: <p>I have a page with 3 buttons.    >Logos >Banners >Footer</p>
  
  <p>When any of these 3 buttons clicked it does jquery post to a page which returns HTML content  in response and I set innerhtml of a div from that returned content . I want to do this so that If I clicked Logo and than went to Banner and come back on Logo it should not request for content again as its already loaded when clicked 1st time.</p>
  
  <p>Thanks .</p>
