It's a solution that shouldn't make problems as white spaces are ignored 
by the server.

It would solve this problem too. (You can also enable TCP Keep alives at 
the client side too, so you don't have to wait for a server that enables 
them.)
But the reason why I suggested this was that it would help to detect 
"orphan connections" at the server side. If a client disconnects without 
logging out of the server or closing the connection to the server (e.g. 
if you network connection just breaks) the server doesn't notice this 
until it tries to send some more data to the client (e.g. a message is 
delivered to the user).
