Yes,

the headers on client side do not arrive until there is also some body content.
So in the quoted code below, due to the little body addition (\0), headers
correctly immediately arrive on client side.

In the documentation :
https://perl.apache.org/docs/2.0/user/coding/coding.html#Forcing_HTTP_Response_Headers_Out
"Apache 2.0 doesn't provide a method to force HTTP response headers sending
(what used to be done by send_http_header() in Apache 1.3).
HTTP response headers are sent as soon as the first bits of the response body
are seen by the special core output filter that generates these headers."
What is strange is that just below this extract is given the rflush example I'm
trying to use.
