43  *    Remove send-wafer and send-vanilla-wafer actions.
44  *

50  *
51  *    Revision 1.30  2008/03/04 18:30:34  fabiankeil
52  *    Remove the treat-forbidden-connects-like-blocks action. We now
53  *    use the "blocked" page for forbidden CONNECT requests by default.
54  *
55  *    Revision 1.29  2008/03/01 14:00:43  fabiankeil
56  *    Let the block action take the reason for the block
57  *    as argument and show it on the "blocked" page.
58  *
59  *    Revision 1.28  2007/12/11 21:08:29  fabiankeil
60  *    Let the CGI editor suggest a forward-override
61  *    parameter whose syntax is actually valid.
62  *
63  *    Revision 1.27  2007/11/10 15:04:08  fabiankeil
64  *    Tell the CGI editor about +hide-referrer{conditional-forge}.
65  *
66  *    Revision 1.26  2007/06/01 16:54:28  fabiankeil
67  *    Add forward-override{} to change the forwarding settings through
68  *    action sections. This is mainly interesting to forward different
69  *    clients differently (for example based on User-Agent or request
70  *    origin).
71  *
72  *    Revision 1.25  2007/04/15 16:39:20  fabiankeil
73  *    Introduce tags as alternative way to specify which
74  *    actions apply to a request. At the moment tags can be
75  *    created based on client and server headers.
76  *
77  *    Revision 1.24  2007/03/20 15:16:34  fabiankeil
78  *    Use dedicated header filter actions instead of abusing "filter".
79  *    Replace "filter-client-headers" and "filter-client-headers"
80  *    with "server-header-filter" and "client-header-filter".
81  *
82  *    Revision 1.23  2006/10/09 10:26:18  fabiankeil
83  *    Changed the path in set-image-blocker's redirection default to
84  *    "send-banner?type=pattern" instead of "show-banner?type=pattern"
85  *    which isn't caught by Privoxy. Fixes BR 1573468.
86  *
87  *    Changed hide-user-agent's default value to "Privoxy VERSION".
88  *
89  *    Changed hide-referrer's default fake value to "http://www.privoxy.org/".
90  *    A static referrer is obviously fake anyway, so we might as well
91  *    advertise ourselves.
92  *
93  *    Revision 1.22  2006/09/01 17:14:18  hal9
94  *    Re-ordered the actions list so that they display in the actions editor in
95  *    alphabetical order. Some of the new actions were "out of order".
96  *
97  *    Revision 1.21  2006/08/14 08:25:19  fabiankeil
98  *    Split filter-headers{} into filter-client-headers{}
99  *    and filter-server-headers{}.
100  *    Added parse_header_time() to share some code.
101  *    Replaced timegm() with mktime().
102  *
103  *    Revision 1.20  2006/08/03 02:46:41  david__schmidt
104  *    Incorporate Fabian Keil's patch work:\rhttp://www.fabiankeil.de/sourcecode/privoxy/
