B4J Question AsyncStreams and POST request: How to send a proper answer?

[KMatle]

I was using an AsynchStreams communication and for fun I had the idea to send a POST request (via OkHttpUtils) from a B4A app to a B4J app which worked like a charm. All data is received well including the http headers.

Now I'm trying to send a proper response back (via the same AsynchStream). The send is working, there are no errors, just a timeout of OkHttpUtils waiting for the response in the B4A app. I send back a string converted to UTF-8 bytes (as I've written: send works, no errors, but no data reaches the app so it times out).

Any ideas here? Do I need to set up headers? I would expect at least "some" data to arrive.

Of course. Example of response: http://www.tcpipguide.com/free/t_HTTPResponseMessageFormat.htm

Pay attention to the empty line. It is important. Note that each line should end with Chr(13) & Chr(10).

For a real http server you should use jServer library.

Yep. It's just "Ok, that works, too?! Wow!"
