* Revisions :
* $Log: loadcfg.c,v $
+ * Revision 1.100 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 1.99 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 1.98 2009/04/24 15:29:43 fabiankeil
+ * Allow to limit the number of of client connections.
+ *
+ * Revision 1.97 2009/04/17 11:45:19 fabiankeil
+ * Replace HAVE_GETADDRINFO and HAVE_GETNAMEINFO macros
+ * with HAVE_RFC2553 macro. Original patch by Petr Pisar.
+ *
+ * Revision 1.96 2009/04/17 11:38:28 fabiankeil
+ * Add and use parse_forwarder_address() to reduce code duplication.
+ *
+ * Revision 1.95 2009/04/17 11:34:34 fabiankeil
+ * Style cosmetics for the IPv6 code.
+ *
+ * Revision 1.94 2009/04/17 11:27:49 fabiankeil
+ * Petr Pisar's privoxy-3.0.12-ipv6-3.diff.
+ *
+ * Revision 1.93 2009/03/18 21:46:26 fabiankeil
+ * Revert the last commit as there's a better way.
+ *
+ * Revision 1.92 2009/03/18 20:43:19 fabiankeil
+ * Don't enable LOG_LEVEL_INFO by default and don't apply the user's
+ * debug settings until the logfile has been opened (if there is one).
+ * Patch submitted by Roland in #2624120.
+ *
+ * Revision 1.91 2009/03/09 17:29:08 fabiankeil
+ * As of r1.88, the show-status page can use a single line for
+ * warnings about ignored directives and the names of the ignored
+ * directives themselves. Reminded by Lee, finally closes #1856559.
+ *
+ * Revision 1.90 2009/03/07 17:58:02 fabiankeil
+ * Fix two mingw32-only buffer overflows. Note that triggering
+ * them requires control over the configuration file in which
+ * case all bets are off anyway.
+ *
* Revision 1.89 2009/03/01 18:46:33 fabiankeil
* - Help clang understand that we aren't
* dereferencing NULL pointers here.
