title: Fastest way to copy text from a File to a HttpServletResponse
body: <p>I need a very fast way to copy text from a file to the body of a HttpServletResponse.</p>
  
  <p>Actually I'm copying byte by byte in a loop, from a bufferedReader to the response.getWriter() but I believe there must be a faster and more straightforward way of doing it.</p>
  
  <p>Thanks!</p>
