QTcpSocket and keep-alive option.

[fanat9]

Can't find how to set keep-alive option for sockets. Is it possible to use with QTcpSocket ?
Any ideas ?

As far as I know, TCP protocol does not provide any keep-alive mechanism. Are you talking about HTTP connection? If so, have you noticed QHttp?

Actually, I already got it working. Although it required some modification of QAbstractSocket and QNativeSocketEngine =)
