__________________________________________________________________________________________________________________________________________________

NAME
Ns_ConnClose - Close an open connection SYNOPSIS
#include "ns.h" int Ns_ConnClose(conn) ARGUMENTS
Ns_Conn conn (in) Pointer to open connection. _________________________________________________________________ DESCRIPTION
This function calls the connection's communication driver to close the connection if it is not already closed. It always returns NS_OK. If the connection is marked for keep-alive, the underlying connection is not actually closed but instead returned to the driver thread to process additional requests, if any. Connections are automatically marked for keep-alive by setting the NS_CONN_KEEPALIVE flag if the client supports it by sending an appropriate connection-keepalive header. Keep alive can be disabled before a call to Ns_ConnClose with the Ns_ConnSetKeepAliveFlag routine with a zero value for the flag argument. SEE ALSO
Ns_ConnSetKeepAliveFlag(3), Ns_ConnGetKeepAliveFlag(3), Ns_ConnFlush(3) KEYWORDS
