62 * with #defines from project.h
64 * Revision 1.18 2001/11/30 23:37:24 jongfoster
65 * Renaming the Win32 config file to config.txt - this is almost the
66 * same as the corresponding UNIX name "config"
68 * Revision 1.17 2001/11/16 00:46:31 jongfoster
69 * Fixing compiler warnings
71 * Revision 1.16 2001/08/01 19:58:12 jongfoster
72 * Fixing documentation filenames in help menu, and making status
73 * option work without needing the "Junkbuster Status.URL" file.
75 * Revision 1.15 2001/07/30 22:08:36 jongfoster
76 * Tidying up #defines:
77 * - All feature #defines are now of the form FEATURE_xxx
78 * - Permanently turned off WIN_GUI_EDIT
79 * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
81 * Revision 1.14 2001/07/29 18:47:05 jongfoster
82 * Adding missing #include "loadcfg.h"

87 * Revision 1.12 2001/07/13 14:04:59 oes
88 * Removed all #ifdef PCRS
90 * Revision 1.11 2001/06/07 23:08:12 jongfoster
91 * Forward and ACL edit options removed.
93 * Revision 1.10 2001/05/31 21:37:11 jongfoster

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

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