<a name="RawSocket"><p></a>
<script>if (window.location.hash) document.writeln('<br>');</script>
A WASD <b>"Raw"Socket</b> is a variant of, and is heavily based on,
the WASD WebSocket infrastructure. It allows a service (listening host and
port) to accept a connection and <b>immediately</b> activate a configured WASD
CGIplus script (in much the same manner as a standard WebSocket script) to
service that connection. Routine library and example applications.
