  40  * Revisions   :
  41  *    $Log: actionlist.h,v $
  42  *    Revision 1.30  2008/03/04 18:30:34  fabiankeil
  43  *    Remove the treat-forbidden-connects-like-blocks action. We now
  44  *    use the "blocked" page for forbidden CONNECT requests by default.
  45  *
  46  *    Revision 1.29  2008/03/01 14:00:43  fabiankeil
  47  *    Let the block action take the reason for the block
  48  *    as argument and show it on the "blocked" page.
  49  *
  50  *    Revision 1.28  2007/12/11 21:08:29  fabiankeil
  51  *    Let the CGI editor suggest a forward-override
  52  *    parameter whose syntax is actually valid.
  53  *
  54  *    Revision 1.27  2007/11/10 15:04:08  fabiankeil
  55  *    Tell the CGI editor about +hide-referrer{conditional-forge}.
  56  *
  57  *    Revision 1.26  2007/06/01 16:54:28  fabiankeil
  58  *    Add forward-override{} to change the forwarding settings through
  59  *    action sections. This is mainly interesting to forward different
  60  *    clients differently (for example based on User-Agent or request
  61  *    origin).
  62  *
  63  *    Revision 1.25  2007/04/15 16:39:20  fabiankeil
  64  *    Introduce tags as alternative way to specify which
  65  *    actions apply to a request. At the moment tags can be
  66  *    created based on client and server headers.
  67  *
  68  *    Revision 1.24  2007/03/20 15:16:34  fabiankeil
  69  *    Use dedicated header filter actions instead of abusing "filter".
  70  *    Replace "filter-client-headers" and "filter-client-headers"
  71  *    with "server-header-filter" and "client-header-filter".
  72  *
  73  *    Revision 1.23  2006/10/09 10:26:18  fabiankeil
  74  *    Changed the path in set-image-blocker's redirection default to
  75  *    "send-banner?type=pattern" instead of "show-banner?type=pattern"
  76  *    which isn't caught by Privoxy. Fixes BR 1573468.
  77  *
  78  *    Changed hide-user-agent's default value to "Privoxy VERSION".
  79  *
  80  *    Changed hide-referrer's default fake value to "http://www.privoxy.org/".
  81  *    A static referrer is obviously fake anyway, so we might as well
  82  *    advertise ourselves.
  83  *
  84  *    Revision 1.22  2006/09/01 17:14:18  hal9
  85  *    Re-ordered the actions list so that they display in the actions editor in
  86  *    alphabetical order. Some of the new actions were "out of order".
  87  *
  88  *    Revision 1.21  2006/08/14 08:25:19  fabiankeil
  89  *    Split filter-headers{} into filter-client-headers{}
  90  *    and filter-server-headers{}.
  91  *    Added parse_header_time() to share some code.
  92  *    Replaced timegm() with mktime().
  93  *
  94  *    Revision 1.20  2006/08/03 02:46:41  david__schmidt
  95  *    Incorporate Fabian Keil's patch work:\rhttp://www.fabiankeil.de/sourcecode/privoxy/
