36 * $Log: showargs.c,v $
37 * Revision 1.22 2001/08/01 00:20:57 jongfoster
38 * Changing show_defines so that it doesn't contain any HTML.
40 * Revision 1.21 2001/07/30 22:08:36 jongfoster
41 * Tidying up #defines:
42 * - All feature #defines are now of the form FEATURE_xxx
43 * - Permanently turned off WIN_GUI_EDIT
44 * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
46 * Revision 1.20 2001/07/18 17:27:22 oes
47 * Adapted to new #defines
49 * Revision 1.19 2001/07/13 14:11:36 oes
50 * - Included SHOW_RCS for deanimate.*
51 * - Removed all #ifdef PCRS
54 * Revision 1.18 2001/07/02 02:55:16 iwanttokeepanon
55 * Apended " on some sites" to the HTML generating function `show_defines' (@ line
56 * 392); since "DENY_GZIP" is not *really* necessary for all PCRS functionallity.
58 * Revision 1.17 2001/06/29 21:45:41 oes
59 * Indentation, CRLF->LF, Tab-> Space
61 * Revision 1.16 2001/06/29 13:35:07 oes
64 * - Removed init_proxy_args
65 * - Renamed end_proxy_args(csp) to show_rcs(void)
66 * - Removed logentry from cancelled commit
67 * - Destroyed support for ndef SPLIT_PROXY_ARGS (Ooops)
68 * - Separated the #define list into show_defines()
70 * Revision 1.15 2001/06/09 10:55:28 jongfoster
71 * Changing BUFSIZ ==> BUFFER_SIZE
73 * Revision 1.14 2001/06/07 23:15:40 jongfoster
74 * Removing config->proxy_args_gateways
75 * Missing return statement added to end_proxy_args().
77 * Revision 1.13 2001/06/06 09:37:59 sarantis
78 * Fix misplaced comment start.
80 * Revision 1.12 2001/06/04 10:41:52 swa
81 * show version string of cgi.h and cgi.c
83 * Revision 1.11 2001/06/03 11:03:48 oes
84 * moved stuff to cgi.c
86 * Revision 1.10 2001/05/31 21:36:07 jongfoster
87 * Added RCS for actions.[ch] and list.[ch]
89 * Revision 1.9 2001/05/29 23:11:38 oes
91 * - Moved strsav() from showargs to miscutil
93 * Revision 1.8 2001/05/29 09:50:24 jongfoster
94 * Unified blocklist/imagelist/permissionslist.
95 * File format is still under discussion, but the internal changes
98 * Also modified interceptor behaviour:
99 * - We now intercept all URLs beginning with one of the following
100 * prefixes (and *only* these prefixes):
102 * * http://ijbswa.sf.net/config/
103 * * http://ijbswa.sourceforge.net/config/
104 * - New interceptors "home page" - go to http://i.j.b/ to see it.
105 * - Internal changes so that intercepted and fast redirect pages
106 * are not replaced with an image.
107 * - Interceptors now have the option to send a binary page direct
108 * to the client. (i.e. ijb-send-banner uses this)
109 * - Implemented show-url-info interceptor. (Which is why I needed
110 * the above interceptors changes - a typical URL is
111 * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
112 * The previous mechanism would not have intercepted that, and
113 * if it had been intercepted then it then it would have replaced
116 * Revision 1.7 2001/05/26 00:28:36 jongfoster
117 * Automatic reloading of config file.
118 * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
119 * Most of the global variables have been moved to a new
120 * struct configuration_spec, accessed through csp->config->globalname
121 * Most of the globals remaining are used by the Win32 GUI.
123 * Revision 1.6 2001/05/25 22:32:56 jongfoster
126 * Revision 1.5 2001/05/22 18:54:49 oes
128 * - Enabled filtering banners by size rather than URL
129 * by adding patterns that replace all standard banner
130 * sizes with the "Junkbuster" gif to the re_filterfile
132 * - Enabled filtering WebBugs by providing a pattern
133 * which kills all 1x1 images
135 * - Added support for PCRE_UNGREEDY behaviour to pcrs,
136 * which is selected by the (nonstandard and therefore
137 * capital) letter 'U' in the option string.
138 * It causes the quantifiers to be ungreedy by default.
139 * Appending a ? turns back to greedy (!).
141 * - Added a new interceptor ijb-send-banner, which
142 * sends back the "Junkbuster" gif. Without imagelist or
143 * MSIE detection support, or if tinygif = 1, or the
144 * URL isn't recognized as an imageurl, a lame HTML
145 * explanation is sent instead.
147 * - Added new feature, which permits blocking remote
148 * script redirects and firing back a local redirect
150 * The feature is conditionally compiled, i.e. it
151 * can be disabled with --disable-fast-redirects,
152 * plus it must be activated by a "fast-redirects"
153 * line in the config file, has its own log level
154 * and of course wants to be displayed by show-proxy-args
155 * Note: Boy, all the #ifdefs in 1001 locations and
156 * all the fumbling with configure.in and acconfig.h
157 * were *way* more work than the feature itself :-(
159 * - Because a generic redirect template was needed for
160 * this, tinygif = 3 now uses the same.
162 * - Moved GIFs, and other static HTTP response templates
167 * - Removed some >400 CRs again (Jon, you really worked
170 * Revision 1.4 2001/05/20 16:44:47 jongfoster
171 * Removing last hardcoded JunkBusters.com URLs.
173 * Revision 1.3 2001/05/20 01:21:20 jongfoster
174 * Version 2.9.4 checkin.
175 * - Merged popupfile and cookiefile, and added control over PCRS
176 * filtering, in new "permissionsfile".
177 * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
178 * file error you now get a message box (in the Win32 GUI) rather
179 * than the program exiting with no explanation.
180 * - Made killpopup use the PCRS MIME-type checking and HTTP-header
182 * - Removed tabs from "config"
183 * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
184 * - Bumped up version number.
186 * Revision 1.2 2001/05/17 23:01:01 oes
187 * - Cleaned CRLF's from the sources and related files
189 * Revision 1.1.1.1 2001/05/15 13:59:03 oes
190 * Initial import of version 2.9.3 source tree
