Hi!

There is no "flush" needed.
If you've got a problem, please describe it in a more detailed way,
including some code lines.

The TCP header have the "P" (push) flag. When I use the boost::asio write()
function, this flag is active?

PUSH flag is the result of TCP_NODELAY socket option.
In asio you can set it with ip::tcp::no_delay.
