NGINX TLS Behavior

[bhaktaonline]

Thanks for the quick response, Sergey,

I set:
    postpone_output 200;

killed/restarted the server

this should have postponed writing output until 200 bytes is available. The
HTTP header is 244 bytes and it should have triggered an output.. I however
still see on single TLS record which has both header and data:

Any suggestions?
