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