  *                using a "gateway" (i.e. HTTP proxy and/or SOCKS4
  *                proxy).  Also contains the list of gateway types.

  * Revisions   :
  *    $Log: gateway.h,v $
+ *    Revision 1.11  2008/11/13 09:08:42  fabiankeil
+ *    Add new config option: keep-alive-timeout.
+ *
+ *    Revision 1.10  2008/10/09 18:21:41  fabiankeil
+ *    Flush work-in-progress changes to keep outgoing connections
+ *    alive where possible. Incomplete and mostly #ifdef'd out.
+ *
+ *    Revision 1.9  2006/07/18 14:48:46  david__schmidt
+ *    Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
+ *    with what was really the latest development (the v_3_0_branch branch)
+ *
+ *    Revision 1.7  2002/03/26 22:29:54  swa
+ *    we have a new homepage!
+ *
+ *    Revision 1.6  2002/03/25 22:12:45  oes
+ *    Added fix for undefined INADDR_NONE on Solaris by Bart Schelstraete
+ *
+ *    Revision 1.5  2002/03/24 13:25:43  swa
+ *    name change related issues
+ *
+ *    Revision 1.4  2002/03/09 20:03:52  jongfoster
+ *    - Making various functions return int rather than size_t.
+ *      (Undoing a recent change).  Since size_t is unsigned on
+ *      Windows, functions like read_socket that return -1 on
+ *      error cannot return a size_t.
+ *
+ *      THIS WAS A MAJOR BUG - it caused frequent, unpredictable
+ *      crashes, and also frequently caused JB to jump to 100%
+ *      CPU and stay there.  (Because it thought it had just
+ *      read ((unsigned)-1) == 4Gb of data...)
+ *
+ *    - The signature of write_socket has changed, it now simply
+ *      returns success=0/failure=nonzero.
+ *
+ *    - Trying to get rid of a few warnings --with-debug on
+ *      Windows, I've introduced a new type "jb_socket".  This is
+ *      used for the socket file descriptors.  On Windows, this
+ *      is SOCKET (a typedef for unsigned).  Everywhere else, it's
+ *      an int.  The error value can't be -1 any more, so it's
+ *      now JB_INVALID_SOCKET (which is -1 on UNIX, and in
+ *      Windows it maps to the #define INVALID_SOCKET.)
+ *
+ *    - The signature of bind_port has changed.
+ *
+ *    Revision 1.3  2001/07/29 18:58:15  jongfoster
+ *    Removing nested #includes, adding forward declarations for needed
+ *    structures, and changing the #define _FILENAME_H to FILENAME_H_INCLUDED.
+ *
+ *    Revision 1.2  2001/06/07 23:12:14  jongfoster
+ *    Removing gateways[] list - no longer used.
+ *    Replacing function pointer in struct gateway with a directly
+ *    called function forwarded_connect(), which can do the common
+ *    task of deciding whether to connect to the web server or HTTP
+ *    proxy.
+ *    Replacing struct gateway with struct forward_spec
+ *
+ *    Revision 1.1.1.1  2001/05/15 13:58:54  oes
+ *    Initial import of version 2.9.3 source tree
