title: how to send variables with sendRedirect()
body: <p>by using the method <code>forward()</code> I can "send" variables  using <code>request.setAttribute()</code>.</p>
  
  <p>What if i should use <code>sendRedirect()</code> instead?? How can i "send" a variable to the destination page?</p>
  
  <p>I don't like to do something like this: <code>sendRedirect("page?varName=varValues")</code>, i don't like to see variables names and values  written on the browser.</p>
  
  <p>Is there a way to send variables in a hidden way when using <code>sendRedirect()</code>?</p>
  
  <p>Thank you</p>
