I slightly modified the tutorial B4J Tutorial [Server] Building web servers with B4J
https://www.b4x.com/android/forum/threads/server-building-web-servers-with-b4j.37172/
When a browser sends a command (http://ServerIP:ServerPort/ToDo?command), I added a "ToDoHandler" which returns a response using
and the browser correctly shows the response.
I then added in the same server an UDP exchange with a second B4J application ; this exchange correctly works in a stand alone mode.
Issue is when I add the UDP exchange (with a WAIT FOR) between the reception of an HTML command and the return of the response. My final response does not get to the browser. I just get a blank page.
I found another thread (Casting an object?) where Erel wrote:
I am not sure it is the same issue : if I send a DB request to my server, the DB response correctly returns to the calling program !
Anyway, how can I return an HTML response to the sender after a WAIT FOR in the Handle Request?
