Boost::Asio Server reads blank message from client, even after the write handle finis

[eubrunomiguel]

I try to write an async message to the server from my client code, the write handler gets called with the correct bytes sent; however, the server receives 0 bytes.

Cliente output:

You received the following message from the server: Sat Aug 20 17:42:01 2016

Server output:

Server is online! 
127.0.0.1:51973 connected!
