* Revisions :
* $Log: gateway.c,v $
+ * Revision 1.51 2009/05/13 18:20:54 fabiankeil
+ * There's no reason for keep_alive_timeout to be signed.
+ *
+ * Revision 1.50 2009/05/10 10:19:23 fabiankeil
+ * Reenable server-side-only keep-alive support, but only share
+ * outgoing connections if the connection-sharing option is set.
+ *
+ * Revision 1.49 2009/05/10 10:12:30 fabiankeil
+ * Initial keep-alive support for the client socket.
+ * Temporarily disable the server-side-only keep-alive code.
+ *
* Revision 1.48 2009/02/13 17:20:36 fabiankeil
* Reword keep-alive support warning and only show
* it #if !defined(HAVE_POLL) && !defined(_WIN32).
