+ *    Help clang understand that we aren't dereferencing
+ *    NULL pointers here.
+ *
+ *    Revision 1.69  2008/09/21 13:36:52  fabiankeil
+ *    If change-x-forwarded-for{add} is used and the client
+ *    sends multiple X-Forwarded-For headers, append the client's
+ *    IP address to each one of them. "Traditionally" we would
+ *    lose all but the last one.
+ *
+ *    Revision 1.68  2008/09/19 15:26:28  fabiankeil
+ *    Add change-x-forwarded-for{} action to block or add
+ *    X-Forwarded-For headers. Mostly based on code removed
+ *    before 3.0.7.
+ *
  *    Revision 1.67  2008/03/30 14:52:08  fabiankeil
  *    Rename load_actions_file() and load_re_filterfile()
  *    as they load multiple files "now".
