var wpage = require('webpage').create(); 
phantom.addCookie ({ 
   'name'    :'cookie1',    /* mandatory property */ 
   'value'   :'1234',       /* mandatory property */ 
   'domain'  :'localhost',  /* mandatory property */ 
   'path'    :'/', 
   'httponly':true, 
   'secure'  :false, 
   'expires' :(new Date()).getTime() + (5000 * 60 * 60) 
}); 

wpage.open('http://localhost/tasks/a.html', function() { 
   console.log("Cookies available are:"); 
   console.log(JSON.stringify(wpage.cookies));  
   wpage.deleteCookie('cookie1'); 
   console.log("Cookies available now after deleting cookie1"); 
   console.log(JSON.stringify(wpage.cookies));
