65 * with #defines from project.h
67 * Revision 1.18 2001/11/30 23:37:24 jongfoster
68 * Renaming the Win32 config file to config.txt - this is almost the
69 * same as the corresponding UNIX name "config"
71 * Revision 1.17 2001/11/16 00:46:31 jongfoster
72 * Fixing compiler warnings
74 * Revision 1.16 2001/08/01 19:58:12 jongfoster
75 * Fixing documentation filenames in help menu, and making status
76 * option work without needing the "Junkbuster Status.URL" file.
78 * Revision 1.15 2001/07/30 22:08:36 jongfoster
79 * Tidying up #defines:
80 * - All feature #defines are now of the form FEATURE_xxx
81 * - Permanently turned off WIN_GUI_EDIT
82 * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS

99 * Revision 1.9 2001/05/31 17:33:13 oes
103 * Revision 1.8 2001/05/29 09:50:24 jongfoster
104 * Unified blocklist/imagelist/permissionslist.
105 * File format is still under discussion, but the internal changes
108 * Also modified interceptor behaviour:
109 * - We now intercept all URLs beginning with one of the following
110 * prefixes (and *only* these prefixes):
112 * * http://ijbswa.sf.net/config/
113 * * http://ijbswa.sourceforge.net/config/
114 * - New interceptors "home page" - go to http://i.j.b/ to see it.
115 * - Internal changes so that intercepted and fast redirect pages
116 * are not replaced with an image.
117 * - Interceptors now have the option to send a binary page direct
118 * to the client. (i.e. ijb-send-banner uses this)
119 * - Implemented show-url-info interceptor. (Which is why I needed
120 * the above interceptors changes - a typical URL is
121 * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
122 * The previous mechanism would not have intercepted that, and
123 * if it had been intercepted then it then it would have replaced
126 * Revision 1.7 2001/05/26 01:26:34 jongfoster
127 * New #define, WIN_GUI_EDIT, enables the (embryonic) Win32 GUI editor.
128 * This #define cannot be set from ./configure - there's no point, it
129 * doesn't work yet. See feature request # 425722
131 * Revision 1.6 2001/05/26 00:31:30 jongfoster
132 * Fixing compiler warning about comparing signed/unsigned.
134 * Revision 1.5 2001/05/26 00:28:36 jongfoster
135 * Automatic reloading of config file.
136 * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
137 * Most of the global variables have been moved to a new
138 * struct configuration_spec, accessed through csp->config->globalname
139 * Most of the globals remaining are used by the Win32 GUI.
141 * Revision 1.4 2001/05/22 18:56:28 oes
144 * Revision 1.3 2001/05/20 15:07:54 jongfoster
145 * File is now ignored if _WIN_CONSOLE is defined.

149 * - Merged popupfile and cookiefile, and added control over PCRS
150 * filtering, in new "permissionsfile".
151 * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
152 * file error you now get a message box (in the Win32 GUI) rather
153 * than the program exiting with no explanation.
154 * - Made killpopup use the PCRS MIME-type checking and HTTP-header
156 * - Removed tabs from "config"
157 * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
158 * - Bumped up version number.
