Can a redirect to relative path be sent from Java Servlet API?

Question

I would like to send relative redirect (to the original request domain & port) to the browser.

Like this:

Location: /app

But Jetty send automatically the full absolute path

Location:http://10.0.2.17:9080/app

The documentation also mentions that the relative URL must be converted to the absolute URL by the servlet container.

Is it even possible to send a relative URL with redirect?

Answer 1

Just manually set the redirect status and header. Replace response.sendRedirect(url) by

response.setStatus(HttpServletResponse.SC_MOVED_TEMPORARILY);
response.setHeader("Location", url);
