Sending back a 401 HTTP response code from the executeFetch?

[user316]

Hello,

There is a certain situation where we would like the client to re-authenticate via RPCManager.setLoginRequiredCallback in the client-side code. For example, if the server turns off and on, we want the user to be prompted to re-login if they send certain DSRequests to the server.

In the server-side code, we want to send back a 401 HTTP response code instead of a normal DSResponse in the executeFetch. This will trigger the client-side code to show the login prompt. How do we cancel the normal DSResponse in the server-side code, and instead send back an HTTP response with the 401 code? The DSResponse.setStatus() does not do it because the HTTP response is still a 200 regardless of the DSResponse status. Thanks.

Also, what do I need to put in the header or body of the HTTP response so that it triggers the setLoginRequiredCallback? It seems I got it to return the 401 code, but this alone isn't triggering the login page.

I used this code:

req.getRPCManager().doCustomResponse();

HttpServletResponse httpServlet = req.getContext().response;
httpServlet.setStatus(401);

I actually got it to work, or to at least show the login prompt. This was my code:

req.getRPCManager().doCustomResponse();

HttpServletResponse httpServlet = req.getContext().response;
httpServlet.getOutputStream().print("<SCRIPT>//'"]]>>isc_loginRequired");
httpServlet.setStatus(401);

Just to close the loop here: yes, that's the correct way to do your own HTTP response, and sending the loginRequired marker is the right way to trigger the relogin flow.
