title: Sending two servlet responses per request
body: <p>I write, because I can not solve the following problem.
  I have a servlet that processes some information.
  In response I put both text and binary content.
  How do I get two response, then two html page, starting from the same request?
  is a thing possible?
  The first response should continue to do what he does now, while the second would appear to make a popup window to save an image.
  There are easier ways to achieve the same result?
  Many thanks in advance</p>
