36 * $Log: showargs.c,v $
37 * Revision 1.19 2001/07/13 14:11:36 oes
38 * - Included SHOW_RCS for deanimate.*
39 * - Removed all #ifdef PCRS
42 * Revision 1.18 2001/07/02 02:55:16 iwanttokeepanon
43 * Apended " on some sites" to the HTML generating function `show_defines' (@ line
44 * 392); since "DENY_GZIP" is not *really* necessary for all PCRS functionallity.
46 * Revision 1.17 2001/06/29 21:45:41 oes
47 * Indentation, CRLF->LF, Tab-> Space
49 * Revision 1.16 2001/06/29 13:35:07 oes
52 * - Removed init_proxy_args
53 * - Renamed end_proxy_args(csp) to show_rcs(void)
54 * - Removed logentry from cancelled commit
55 * - Destroyed support for ndef SPLIT_PROXY_ARGS (Ooops)
56 * - Separated the #define list into show_defines()
58 * Revision 1.15 2001/06/09 10:55:28 jongfoster
59 * Changing BUFSIZ ==> BUFFER_SIZE
61 * Revision 1.14 2001/06/07 23:15:40 jongfoster
62 * Removing config->proxy_args_gateways
63 * Missing return statement added to end_proxy_args().
65 * Revision 1.13 2001/06/06 09:37:59 sarantis
66 * Fix misplaced comment start.
68 * Revision 1.12 2001/06/04 10:41:52 swa
69 * show version string of cgi.h and cgi.c
71 * Revision 1.11 2001/06/03 11:03:48 oes
72 * moved stuff to cgi.c
74 * Revision 1.10 2001/05/31 21:36:07 jongfoster
75 * Added RCS for actions.[ch] and list.[ch]
77 * Revision 1.9 2001/05/29 23:11:38 oes
79 * - Moved strsav() from showargs to miscutil
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 00:28:36 jongfoster
105 * Automatic reloading of config file.
106 * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
107 * Most of the global variables have been moved to a new
108 * struct configuration_spec, accessed through csp->config->globalname
109 * Most of the globals remaining are used by the Win32 GUI.
111 * Revision 1.6 2001/05/25 22:32:56 jongfoster
114 * Revision 1.5 2001/05/22 18:54:49 oes
116 * - Enabled filtering banners by size rather than URL
117 * by adding patterns that replace all standard banner
118 * sizes with the "Junkbuster" gif to the re_filterfile
120 * - Enabled filtering WebBugs by providing a pattern
121 * which kills all 1x1 images
123 * - Added support for PCRE_UNGREEDY behaviour to pcrs,
124 * which is selected by the (nonstandard and therefore
125 * capital) letter 'U' in the option string.
126 * It causes the quantifiers to be ungreedy by default.
127 * Appending a ? turns back to greedy (!).
129 * - Added a new interceptor ijb-send-banner, which
130 * sends back the "Junkbuster" gif. Without imagelist or
131 * MSIE detection support, or if tinygif = 1, or the
132 * URL isn't recognized as an imageurl, a lame HTML
133 * explanation is sent instead.
135 * - Added new feature, which permits blocking remote
136 * script redirects and firing back a local redirect
138 * The feature is conditionally compiled, i.e. it
139 * can be disabled with --disable-fast-redirects,
140 * plus it must be activated by a "fast-redirects"
141 * line in the config file, has its own log level
142 * and of course wants to be displayed by show-proxy-args
143 * Note: Boy, all the #ifdefs in 1001 locations and
144 * all the fumbling with configure.in and acconfig.h
145 * were *way* more work than the feature itself :-(
147 * - Because a generic redirect template was needed for
148 * this, tinygif = 3 now uses the same.
150 * - Moved GIFs, and other static HTTP response templates
155 * - Removed some >400 CRs again (Jon, you really worked
158 * Revision 1.4 2001/05/20 16:44:47 jongfoster
159 * Removing last hardcoded JunkBusters.com URLs.
161 * Revision 1.3 2001/05/20 01:21:20 jongfoster
162 * Version 2.9.4 checkin.
163 * - Merged popupfile and cookiefile, and added control over PCRS
164 * filtering, in new "permissionsfile".
165 * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
166 * file error you now get a message box (in the Win32 GUI) rather
167 * than the program exiting with no explanation.
168 * - Made killpopup use the PCRS MIME-type checking and HTTP-header
170 * - Removed tabs from "config"
171 * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
172 * - Bumped up version number.
174 * Revision 1.2 2001/05/17 23:01:01 oes
175 * - Cleaned CRLF's from the sources and related files
177 * Revision 1.1.1.1 2001/05/15 13:59:03 oes
178 * Initial import of version 2.9.3 source tree
