title: Does sendRedirect() happens at client side or at the server side?
body: <p>The theory says that 
  <strong><em>A request dispatch happens on the server, while a redirect happens on
   the client.</em></strong>
  <br/><br/>
  Aren't that the both methods used in the servlet? Then both should happen at server side. Right? 
  <br/>
  Or did i misunderstood what is client/server side? <br/> Please give me clear explanation with some examples if you can. 
  <br/>
  Thank you. </p>
