46 * - Add exit message to logfile (unix)
48 * Revision 1.12 2001/11/07 00:02:13 steudten
49 * Add line number in error output for lineparsing for

51 * Special handling for CLF added.
53 * Revision 1.11 2001/10/23 21:38:53 jongfoster
54 * Adding error-checking to create_url_spec()
56 * Revision 1.10 2001/09/22 16:36:59 jongfoster
57 * Removing unused parameter fs from read_config_line()
59 * Revision 1.9 2001/07/30 22:08:36 jongfoster
60 * Tidying up #defines:
61 * - All feature #defines are now of the form FEATURE_xxx
62 * - Permanently turned off WIN_GUI_EDIT
63 * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
65 * Revision 1.8 2001/07/29 18:58:15 jongfoster
66 * Removing nested #includes, adding forward declarations for needed
67 * structures, and changing the #define _FILENAME_H to FILENAME_H_INCLUDED.
69 * Revision 1.7 2001/07/13 14:01:54 oes
70 * Removed all #ifdef PCRS
72 * Revision 1.6 2001/06/07 23:14:38 jongfoster
73 * Removing ACL and forward file loaders - these files have
74 * been merged into the config file.
76 * Revision 1.5 2001/05/31 21:28:49 jongfoster
77 * Removed all permissionsfile code - it's now called the actions
78 * file, and (almost) all the code is in actions.c
80 * Revision 1.4 2001/05/29 09:50:24 jongfoster
81 * Unified blocklist/imagelist/permissionslist.
82 * File format is still under discussion, but the internal changes
85 * Also modified interceptor behaviour:
86 * - We now intercept all URLs beginning with one of the following
87 * prefixes (and *only* these prefixes):
89 * * http://ijbswa.sf.net/config/
90 * * http://ijbswa.sourceforge.net/config/
91 * - New interceptors "home page" - go to http://i.j.b/ to see it.
92 * - Internal changes so that intercepted and fast redirect pages
93 * are not replaced with an image.
94 * - Interceptors now have the option to send a binary page direct
95 * to the client. (i.e. ijb-send-banner uses this)
96 * - Implemented show-url-info interceptor. (Which is why I needed
97 * the above interceptors changes - a typical URL is
98 * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
99 * The previous mechanism would not have intercepted that, and
100 * if it had been intercepted then it then it would have replaced
103 * Revision 1.3 2001/05/26 00:28:36 jongfoster
104 * Automatic reloading of config file.
105 * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
106 * Most of the global variables have been moved to a new
107 * struct configuration_spec, accessed through csp->config->globalname
108 * Most of the globals remaining are used by the Win32 GUI.
110 * Revision 1.2 2001/05/20 01:21:20 jongfoster
111 * Version 2.9.4 checkin.
112 * - Merged popupfile and cookiefile, and added control over PCRS
113 * filtering, in new "permissionsfile".
114 * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
115 * file error you now get a message box (in the Win32 GUI) rather
116 * than the program exiting with no explanation.
117 * - Made killpopup use the PCRS MIME-type checking and HTTP-header
119 * - Removed tabs from "config"
120 * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
121 * - Bumped up version number.
123 * Revision 1.1.1.1 2001/05/15 13:59:00 oes
124 * Initial import of version 2.9.3 source tree
