   <head>
      <title>welcome to phantomjs</title>
   </head> 

   <body name = "content"> 
      <script type = "text/javascript"> 
         window.name = "page2"; 
         console.log('welcome to cookie example'); 
         document.cookie = "username = Roy; expires = Thu, 22 Dec 2017 12:00:00 UTC"; 

         window.onload =  function() { 
            console.log("page is loaded"); 
         } 
      </script> 

      <iframe src = "http://localhost/tasks/a.html" width = "800" height = "800" 
         name = "myframe" id = "myframe"></iframe> 
      <iframe src = "http://localhost/tasks/alert.html" width = "800" height = "800" 
         name = "myframe1" id = "myframe1"></iframe>
