36 * - "Show Privoxy Window" now a toggle
37 * - Temp kludge to let user and default action file be edited through win32 GUI (FR 592080)

45 * Revision 1.23 2002/03/26 22:57:10 jongfoster
46 * Web server name should begin www.
48 * Revision 1.22 2002/03/24 12:48:23 jongfoster
51 * Revision 1.21 2002/03/24 12:07:35 jongfoster
52 * Consistern name for filters file
54 * Revision 1.20 2002/03/24 12:03:47 jongfoster
57 * Revision 1.19 2002/01/17 21:04:17 jongfoster
58 * Replacing hard references to the URL of the config interface
59 * with #defines from project.h
61 * Revision 1.18 2001/11/30 23:37:24 jongfoster
62 * Renaming the Win32 config file to config.txt - this is almost the
63 * same as the corresponding UNIX name "config"
65 * Revision 1.17 2001/11/16 00:46:31 jongfoster
66 * Fixing compiler warnings
68 * Revision 1.16 2001/08/01 19:58:12 jongfoster
69 * Fixing documentation filenames in help menu, and making status
70 * option work without needing the "Junkbuster Status.URL" file.
72 * Revision 1.15 2001/07/30 22:08:36 jongfoster
73 * Tidying up #defines:
74 * - All feature #defines are now of the form FEATURE_xxx
75 * - Permanently turned off WIN_GUI_EDIT
76 * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
78 * Revision 1.14 2001/07/29 18:47:05 jongfoster
79 * Adding missing #include "loadcfg.h"
81 * Revision 1.13 2001/07/19 19:15:14 haroon
82 * - Added a FIXME for EditFile but didn't fix :-)
84 * Revision 1.12 2001/07/13 14:04:59 oes
85 * Removed all #ifdef PCRS
87 * Revision 1.11 2001/06/07 23:08:12 jongfoster
88 * Forward and ACL edit options removed.
90 * Revision 1.10 2001/05/31 21:37:11 jongfoster
91 * GUI changes to rename "permissions file" to "actions file".
93 * Revision 1.9 2001/05/31 17:33:13 oes
97 * Revision 1.8 2001/05/29 09:50:24 jongfoster
98 * Unified blocklist/imagelist/permissionslist.
99 * File format is still under discussion, but the internal changes
102 * Also modified interceptor behaviour:
103 * - We now intercept all URLs beginning with one of the following
104 * prefixes (and *only* these prefixes):
106 * * http://ijbswa.sf.net/config/
107 * * http://ijbswa.sourceforge.net/config/
108 * - New interceptors "home page" - go to http://i.j.b/ to see it.
109 * - Internal changes so that intercepted and fast redirect pages
110 * are not replaced with an image.
111 * - Interceptors now have the option to send a binary page direct
112 * to the client. (i.e. ijb-send-banner uses this)
113 * - Implemented show-url-info interceptor. (Which is why I needed
114 * the above interceptors changes - a typical URL is
115 * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
116 * The previous mechanism would not have intercepted that, and
117 * if it had been intercepted then it then it would have replaced
120 * Revision 1.7 2001/05/26 01:26:34 jongfoster
121 * New #define, WIN_GUI_EDIT, enables the (embryonic) Win32 GUI editor.
122 * This #define cannot be set from ./configure - there's no point, it
123 * doesn't work yet. See feature request # 425722
125 * Revision 1.6 2001/05/26 00:31:30 jongfoster
126 * Fixing compiler warning about comparing signed/unsigned.
128 * Revision 1.5 2001/05/26 00:28:36 jongfoster
129 * Automatic reloading of config file.
130 * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
131 * Most of the global variables have been moved to a new
132 * struct configuration_spec, accessed through csp->config->globalname
133 * Most of the globals remaining are used by the Win32 GUI.
135 * Revision 1.4 2001/05/22 18:56:28 oes
138 * Revision 1.3 2001/05/20 15:07:54 jongfoster
139 * File is now ignored if _WIN_CONSOLE is defined.
141 * Revision 1.2 2001/05/20 01:21:20 jongfoster
142 * Version 2.9.4 checkin.
143 * - Merged popupfile and cookiefile, and added control over PCRS
144 * filtering, in new "permissionsfile".
145 * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
146 * file error you now get a message box (in the Win32 GUI) rather
147 * than the program exiting with no explanation.
148 * - Made killpopup use the PCRS MIME-type checking and HTTP-header
150 * - Removed tabs from "config"
151 * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
152 * - Bumped up version number.
154 * Revision 1.1.1.1 2001/05/15 13:59:07 oes
155 * Initial import of version 2.9.3 source tree
