title: How can I use persisted cookies from a file using phantomjs
body: <p>I have some authentication requried to hit a particular url. In browser I need to login only once, as for other related urls which can use the session id from the cookie need not required to go to the login page. 
  Similarly, can I use the cookie generated in the cookie file using <code>--cookies-file=cookies.txt</code> in the commandline in phantomjs to open other page which requires the same cookie detail.</p>
  
  <p>Please suggest.</p>
