+ *    Revision 1.13  2009/05/10 10:12:30  fabiankeil
+ *    Initial keep-alive support for the client socket.

+ *    Revision 1.12  2008/12/24 17:06:19  fabiankeil
+ *    Keep a thread around to timeout alive connections
+ *    even if no new requests are coming in.

+ *    Add new config option: keep-alive-timeout.

  *    Revision 1.9  2006/07/18 14:48:46  david__schmidt
  *    Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
