36 * $Log: showargs.c,v $
37 * Revision 1.24 2001/08/05 16:06:20 jongfoster
38 * Modifiying "struct map" so that there are now separate header and
39 * "map_entry" structures. This means that functions which modify a
40 * map no longer need to return a pointer to the modified map.
41 * Also, it no longer reverses the order of the entries (which may be
42 * important with some advanced template substitutions).
44 * Revision 1.23 2001/08/02 22:03:23 jongfoster
45 * Fixing an unterminated character constant.
47 * Revision 1.22 2001/08/01 00:20:57 jongfoster
48 * Changing show_defines so that it doesn't contain any HTML.
50 * Revision 1.21 2001/07/30 22:08:36 jongfoster
51 * Tidying up #defines:
52 * - All feature #defines are now of the form FEATURE_xxx
53 * - Permanently turned off WIN_GUI_EDIT
54 * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
56 * Revision 1.20 2001/07/18 17:27:22 oes
57 * Adapted to new #defines
59 * Revision 1.19 2001/07/13 14:11:36 oes
60 * - Included SHOW_RCS for deanimate.*
61 * - Removed all #ifdef PCRS
64 * Revision 1.18 2001/07/02 02:55:16 iwanttokeepanon
65 * Apended " on some sites" to the HTML generating function `show_defines' (@ line
66 * 392); since "DENY_GZIP" is not *really* necessary for all PCRS functionallity.
68 * Revision 1.17 2001/06/29 21:45:41 oes
69 * Indentation, CRLF->LF, Tab-> Space
71 * Revision 1.16 2001/06/29 13:35:07 oes
74 * - Removed init_proxy_args
75 * - Renamed end_proxy_args(csp) to show_rcs(void)
76 * - Removed logentry from cancelled commit
77 * - Destroyed support for ndef SPLIT_PROXY_ARGS (Ooops)
78 * - Separated the #define list into show_defines()
80 * Revision 1.15 2001/06/09 10:55:28 jongfoster
81 * Changing BUFSIZ ==> BUFFER_SIZE
83 * Revision 1.14 2001/06/07 23:15:40 jongfoster
84 * Removing config->proxy_args_gateways
85 * Missing return statement added to end_proxy_args().
87 * Revision 1.13 2001/06/06 09:37:59 sarantis
88 * Fix misplaced comment start.
90 * Revision 1.12 2001/06/04 10:41:52 swa
91 * show version string of cgi.h and cgi.c
93 * Revision 1.11 2001/06/03 11:03:48 oes
94 * moved stuff to cgi.c
96 * Revision 1.10 2001/05/31 21:36:07 jongfoster
97 * Added RCS for actions.[ch] and list.[ch]
99 * Revision 1.9 2001/05/29 23:11:38 oes
101 * - Moved strsav() from showargs to miscutil
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 00:28:36 jongfoster
127 * Automatic reloading of config file.
128 * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
129 * Most of the global variables have been moved to a new
130 * struct configuration_spec, accessed through csp->config->globalname
131 * Most of the globals remaining are used by the Win32 GUI.
133 * Revision 1.6 2001/05/25 22:32:56 jongfoster
136 * Revision 1.5 2001/05/22 18:54:49 oes
138 * - Enabled filtering banners by size rather than URL
139 * by adding patterns that replace all standard banner
140 * sizes with the "Junkbuster" gif to the re_filterfile
142 * - Enabled filtering WebBugs by providing a pattern
143 * which kills all 1x1 images
145 * - Added support for PCRE_UNGREEDY behaviour to pcrs,
146 * which is selected by the (nonstandard and therefore
147 * capital) letter 'U' in the option string.
148 * It causes the quantifiers to be ungreedy by default.
149 * Appending a ? turns back to greedy (!).
151 * - Added a new interceptor ijb-send-banner, which
152 * sends back the "Junkbuster" gif. Without imagelist or
153 * MSIE detection support, or if tinygif = 1, or the
154 * URL isn't recognized as an imageurl, a lame HTML
155 * explanation is sent instead.
157 * - Added new feature, which permits blocking remote
158 * script redirects and firing back a local redirect
160 * The feature is conditionally compiled, i.e. it
161 * can be disabled with --disable-fast-redirects,
162 * plus it must be activated by a "fast-redirects"
163 * line in the config file, has its own log level
164 * and of course wants to be displayed by show-proxy-args
165 * Note: Boy, all the #ifdefs in 1001 locations and
166 * all the fumbling with configure.in and acconfig.h
167 * were *way* more work than the feature itself :-(
169 * - Because a generic redirect template was needed for
170 * this, tinygif = 3 now uses the same.
172 * - Moved GIFs, and other static HTTP response templates
177 * - Removed some >400 CRs again (Jon, you really worked
180 * Revision 1.4 2001/05/20 16:44:47 jongfoster
181 * Removing last hardcoded JunkBusters.com URLs.
183 * Revision 1.3 2001/05/20 01:21:20 jongfoster
184 * Version 2.9.4 checkin.
185 * - Merged popupfile and cookiefile, and added control over PCRS
186 * filtering, in new "permissionsfile".
187 * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
188 * file error you now get a message box (in the Win32 GUI) rather
189 * than the program exiting with no explanation.
190 * - Made killpopup use the PCRS MIME-type checking and HTTP-header
192 * - Removed tabs from "config"
193 * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
194 * - Bumped up version number.
196 * Revision 1.2 2001/05/17 23:01:01 oes
197 * - Cleaned CRLF's from the sources and related files
199 * Revision 1.1.1.1 2001/05/15 13:59:03 oes
200 * Initial import of version 2.9.3 source tree
