Question

I am using the embedded version of jetty. I have noticed the following:

in the handler method, if I want to directly respond with an HTTP OK response, then sleep for x seconds, the handler is doing the opposite. Is this normal?

the handle function is the following:

public void handle(String target, Request baseRequest, HttpServletRequest request, HttpServletResponse response)
            throws IOException, ServletException {

response.setContentType("text/html;charset=utf-8");
            response.setStatus(HttpServletResponse.SC_OK);
            baseRequest.setHandled(true);
            response.getWriter().println("OK");

Thread.sleep(10000);

}

The bastard is sleeping 10 seconds then returning the response, why is this happening?

Answer 1

You need to call

response.flushBuffer();

before you sleep the Thread.

From the JavaDoc of this method:

Forces any content in the buffer to be written to the client. A call
to this method automatically commits the response, meaning the status
code and headers will be written.
