+ * Revision 1.133 2009/04/24 15:29:43 fabiankeil
+ * Allow to limit the number of of client connections.
+ *
+ * Revision 1.132 2009/04/17 11:45:19 fabiankeil
+ * Replace HAVE_GETADDRINFO and HAVE_GETNAMEINFO macros
+ * with HAVE_RFC2553 macro. Original patch by Petr Pisar.
+ *
+ * Revision 1.131 2009/04/17 11:34:35 fabiankeil
+ * Style cosmetics for the IPv6 code.
+ *
+ * Revision 1.130 2009/04/17 11:27:49 fabiankeil
+ * Petr Pisar's privoxy-3.0.12-ipv6-3.diff.
+ *
+ * Revision 1.129 2009/03/08 14:12:51 fabiankeil
+ * All the CSP_FLAG_FOO bit masks should be unsigned ints.
+ *
+ * Revision 1.128 2009/03/07 13:09:17 fabiankeil
+ * Change csp->expected_content and_csp->expected_content_length from
+ * size_t to unsigned long long to reduce the likelihood of integer
+ * overflows that would let us close the connection prematurely.
+ * Bug found while investigating #2669131, reported by cyberpatrol.
+ *
* Revision 1.127 2008/12/20 14:53:55 fabiankeil
* Add config option socket-timeout to control the time
* Privoxy waits for data to arrive on a socket. Useful
