	These parameters affect how ''[[Janus Sockets]]'' applications respond to a closed connection. If the remote host closes the connection, even if it does so "cleanly" (that is with FIN rather than RESET), ''Janus Sockets'' closes the connection immediately.

This is useful in situations where FIN is as good as RESET for rendering a connection unusable, and where it's important to know that a FIN has been sent to avoid wasted processing or even a hung connection.

	If <var>FINCLOSE</var> is not specified, or if <var>NOFINCLOSE</var> is specified, a ''Janus Sockets'' thread remains in-use and does not recognize a FIN indicator sent by a remote partner until the ''Janus Sockets'' application tries to receive data on the connection.		If <var>FINCLOSE</var> is not specified, or if <var>NOFINCLOSE</var> is specified, a <var class="product">Janus Sockets</var> thread remains in-use and does not recognize a FIN indicator sent by a remote partner until the <var class="product">Janus Sockets</var> application tries to receive data on the connection.

	A situation where <var>FINCLOSE</var> processing is useful is a ''Janus Sockets'' application communicating with a web server that is using a keep-alive facility (multiple requests over the same TCP/IP connection). The web server could close the connection between any pair of requests with a FIN. Without <var>FINCLOSE</var> processing, a Janus thread that connected to the web server and received such a FIN would remain in use until the ''Janus Sockets'' application tried to receive data on the connection and then noticed the closed connection.

	If not set on the port definition, you can make <var>FINCLOSE</var> or <var>NOFINCLOSE</var> specific to a <var>[[$Sock_Conn]]</var> call or to a <var>[[Socket class\|Socket]]</var> object <var>[[New (Socket constructor)\|New]]</var> constructor.
