This is flatly wrong. Unless you have enabled SO_KEEPALIVE, or you have
older TCP/IP stacks with bugs, TCP connections *can* and *do* survive 24
hours of interruption in network connectivity.

If the application generates no traffic (and in the absence of keepalives), 
there are *no* packets flowing on an idle TCP connection. Please cite the
specific places in the RFCs you think demand that such a connection should
be torn down just because there is a temporary interruption in connectivity
between the end points.
