37 * Revision 1.21 2001/07/30 22:08:36 jongfoster
38 * Tidying up #defines:
39 * - All feature #defines are now of the form FEATURE_xxx
40 * - Permanently turned off WIN_GUI_EDIT
41 * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
43 * Revision 1.20 2001/07/18 17:27:22 oes
44 * Adapted to new #defines
46 * Revision 1.19 2001/07/13 14:11:36 oes
47 * - Included SHOW_RCS for deanimate.*
48 * - Removed all #ifdef PCRS
51 * Revision 1.18 2001/07/02 02:55:16 iwanttokeepanon
52 * Apended " on some sites" to the HTML generating function `show_defines' (@ line
53 * 392); since "DENY_GZIP" is not *really* necessary for all PCRS functionallity.
55 * Revision 1.17 2001/06/29 21:45:41 oes
56 * Indentation, CRLF->LF, Tab-> Space
58 * Revision 1.16 2001/06/29 13:35:07 oes
61 * - Removed init_proxy_args
62 * - Renamed end_proxy_args(csp) to show_rcs(void)
63 * - Removed logentry from cancelled commit
64 * - Destroyed support for ndef SPLIT_PROXY_ARGS (Ooops)
65 * - Separated the #define list into show_defines()
67 * Revision 1.15 2001/06/09 10:55:28 jongfoster
68 * Changing BUFSIZ ==> BUFFER_SIZE
70 * Revision 1.14 2001/06/07 23:15:40 jongfoster
71 * Removing config->proxy_args_gateways
72 * Missing return statement added to end_proxy_args().
74 * Revision 1.13 2001/06/06 09:37:59 sarantis
75 * Fix misplaced comment start.
77 * Revision 1.12 2001/06/04 10:41:52 swa
78 * show version string of cgi.h and cgi.c
80 * Revision 1.11 2001/06/03 11:03:48 oes
81 * moved stuff to cgi.c
83 * Revision 1.10 2001/05/31 21:36:07 jongfoster
84 * Added RCS for actions.[ch] and list.[ch]
86 * Revision 1.9 2001/05/29 23:11:38 oes
88 * - Moved strsav() from showargs to miscutil
90 * Revision 1.8 2001/05/29 09:50:24 jongfoster
91 * Unified blocklist/imagelist/permissionslist.
92 * File format is still under discussion, but the internal changes
95 * Also modified interceptor behaviour:
96 * - We now intercept all URLs beginning with one of the following
97 * prefixes (and *only* these prefixes):
99 * * http://ijbswa.sf.net/config/
100 * * http://ijbswa.sourceforge.net/config/
101 * - New interceptors "home page" - go to http://i.j.b/ to see it.
102 * - Internal changes so that intercepted and fast redirect pages
103 * are not replaced with an image.
104 * - Interceptors now have the option to send a binary page direct
105 * to the client. (i.e. ijb-send-banner uses this)
106 * - Implemented show-url-info interceptor. (Which is why I needed
107 * the above interceptors changes - a typical URL is
108 * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
109 * The previous mechanism would not have intercepted that, and
110 * if it had been intercepted then it then it would have replaced
113 * Revision 1.7 2001/05/26 00:28:36 jongfoster
114 * Automatic reloading of config file.
115 * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
116 * Most of the global variables have been moved to a new
117 * struct configuration_spec, accessed through csp->config->globalname
118 * Most of the globals remaining are used by the Win32 GUI.
120 * Revision 1.6 2001/05/25 22:32:56 jongfoster
123 * Revision 1.5 2001/05/22 18:54:49 oes
125 * - Enabled filtering banners by size rather than URL
126 * by adding patterns that replace all standard banner
127 * sizes with the "Junkbuster" gif to the re_filterfile
129 * - Enabled filtering WebBugs by providing a pattern
130 * which kills all 1x1 images
132 * - Added support for PCRE_UNGREEDY behaviour to pcrs,
133 * which is selected by the (nonstandard and therefore
134 * capital) letter 'U' in the option string.
135 * It causes the quantifiers to be ungreedy by default.
136 * Appending a ? turns back to greedy (!).
138 * - Added a new interceptor ijb-send-banner, which
139 * sends back the "Junkbuster" gif. Without imagelist or
140 * MSIE detection support, or if tinygif = 1, or the
141 * URL isn't recognized as an imageurl, a lame HTML
142 * explanation is sent instead.
144 * - Added new feature, which permits blocking remote
145 * script redirects and firing back a local redirect
147 * The feature is conditionally compiled, i.e. it
148 * can be disabled with --disable-fast-redirects,
149 * plus it must be activated by a "fast-redirects"
150 * line in the config file, has its own log level
151 * and of course wants to be displayed by show-proxy-args
152 * Note: Boy, all the #ifdefs in 1001 locations and
153 * all the fumbling with configure.in and acconfig.h
154 * were *way* more work than the feature itself :-(
156 * - Because a generic redirect template was needed for
157 * this, tinygif = 3 now uses the same.
159 * - Moved GIFs, and other static HTTP response templates
164 * - Removed some >400 CRs again (Jon, you really worked
167 * Revision 1.4 2001/05/20 16:44:47 jongfoster
168 * Removing last hardcoded JunkBusters.com URLs.
170 * Revision 1.3 2001/05/20 01:21:20 jongfoster
171 * Version 2.9.4 checkin.
172 * - Merged popupfile and cookiefile, and added control over PCRS
173 * filtering, in new "permissionsfile".
174 * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
175 * file error you now get a message box (in the Win32 GUI) rather
176 * than the program exiting with no explanation.
177 * - Made killpopup use the PCRS MIME-type checking and HTTP-header
179 * - Removed tabs from "config"
180 * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
181 * - Bumped up version number.
183 * Revision 1.2 2001/05/17 23:01:01 oes
184 * - Cleaned CRLF's from the sources and related files
186 * Revision 1.1.1.1 2001/05/15 13:59:03 oes
187 * Initial import of version 2.9.3 source tree
