34 dnl Revision 1.19 2001/10/07 15:33:14 oes
35 dnl Removed FEATURE_DENY_GZIP
36 dnl Bumped up version number
38 dnl Revision 1.18 2001/09/13 13:10:24 steudten
40 dnl PreWork for Debug Interface.
41 dnl Add new option "--with-debug" to enable debugging (flags aso.)
43 dnl Revision 1.17 2001/09/12 23:44:55 david__schmidt
44 dnl Mac OSX (Darwin) support added.
46 dnl Revision 1.16 2001/09/12 22:55:45 joergs
47 dnl AmigaOS support added.
49 dnl Revision 1.15 2001/09/12 17:28:59 david__schmidt
51 dnl OS/2 port: update autoconf'd support for the platform.
53 dnl Revision 1.14 2001/07/30 22:12:11 jongfoster
54 dnl Fixing Solaris build (I hope) and tidying up #defines:
55 dnl - All feature #defines are now of the form FEATURE_xxx
56 dnl - Permanently turned off WIN_GUI_EDIT
57 dnl - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
59 dnl Revision 1.13 2001/07/29 17:09:17 jongfoster
60 dnl Major changes to build system in order to fix these bugs:
61 dnl - pthreads under Linux was broken - changed -lpthread to -pthread
62 dnl - Compiling in MinGW32 mode under CygWin now correctly detects
63 dnl which shared libraries are available
64 dnl - Solaris support (?) (Not tested under Solaris yet)
66 dnl Revision 1.12 2001/07/25 19:16:27 oes
67 dnl Bumping version number to 2.9.8
69 dnl Revision 1.11 2001/07/21 18:00:07 jongfoster
70 dnl Bumping version number to 2.9.7
72 dnl Revision 1.10 2001/07/18 17:25:04 oes
75 dnl Revision 1.9 2001/07/15 19:45:13 jongfoster
76 dnl Added support for linking with POSIX threads library
78 dnl Revision 1.8 2001/07/15 17:54:29 jongfoster
79 dnl Renaming #define STATIC to STATIC_PCRE
80 dnl Adding new #define FEATURE_PTHREAD that will be used to enable
81 dnl POSIX threads support.
83 dnl Revision 1.7 2001/07/13 13:58:05 oes
84 dnl Completely reorganized the selection scheme for
85 dnl pcre, pcreposix, pcrs and gnu_regex:
87 dnl The presence of shared pcre, pcreposix or pcrs
88 dnl libraried is now autodetected. Additionally, the
89 dnl user can enforce using the built-in static variants
90 dnl by specifying --disable-dynamic-(pcre|pcrs).
91 dnl Care is taken to avoid that pcre is dyn, while pcreposix
92 dnl is static, if both are used and that pcrs is static if
95 dnl The choice between pcre, gnu or no regex for actionsfile
96 dnl URL matching is now via
97 dnl --(enable|disable)-regex-matching[=(gnu|pcre|no)] with the
98 dnl default being pcre.
100 dnl Revision 1.6 2001/06/29 21:56:40 oes
103 dnl Revision 1.5 2001/06/29 13:26:27 oes
104 dnl Introduced #define CODE_STATUS
106 dnl Revision 1.4 2001/05/29 09:50:24 jongfoster
107 dnl Unified blocklist/imagelist/permissionslist.
108 dnl File format is still under discussion, but the internal changes
109 dnl are (mostly) done.
111 dnl Also modified interceptor behaviour:
112 dnl - We now intercept all URLs beginning with one of the following
113 dnl prefixes (and *only* these prefixes):
115 dnl * http://ijbswa.sf.net/config/
116 dnl * http://ijbswa.sourceforge.net/config/
117 dnl - New interceptors "home page" - go to http://i.j.b/ to see it.
118 dnl - Internal changes so that intercepted and fast redirect pages
119 dnl are not replaced with an image.
120 dnl - Interceptors now have the option to send a binary page direct
121 dnl to the client. (i.e. ijb-send-banner uses this)
122 dnl - Implemented show-url-info interceptor. (Which is why I needed
123 dnl the above interceptors changes - a typical URL is
124 dnl "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
125 dnl The previous mechanism would not have intercepted that, and
126 dnl if it had been intercepted then it then it would have replaced
127 dnl it with an image.)
129 dnl Revision 1.3 2001/05/22 18:46:04 oes
131 dnl - Enabled filtering banners by size rather than URL
132 dnl by adding patterns that replace all standard banner
133 dnl sizes with the "Junkbuster" gif to the re_filterfile
135 dnl - Enabled filtering WebBugs by providing a pattern
136 dnl which kills all 1x1 images
138 dnl - Added support for PCRE_UNGREEDY behaviour to pcrs,
139 dnl which is selected by the (nonstandard and therefore
140 dnl capital) letter 'U' in the option string.
141 dnl It causes the quantifiers to be ungreedy by default.
142 dnl Appending a ? turns back to greedy (!).
144 dnl - Added a new interceptor ijb-send-banner, which
145 dnl sends back the "Junkbuster" gif. Without imagelist or
146 dnl MSIE detection support, or if tinygif = 1, or the
147 dnl URL isn't recognized as an imageurl, a lame HTML
148 dnl explanation is sent instead.
150 dnl - Added new feature, which permits blocking remote
151 dnl script redirects and firing back a local redirect
153 dnl The feature is conditionally compiled, i.e. it
154 dnl can be disabled with --disable-fast-redirects,
155 dnl plus it must be activated by a "fast-redirects"
156 dnl line in the config file, has its own log level
157 dnl and of course wants to be displayed by show-proxy-args
158 dnl Note: Boy, all the #ifdefs in 1001 locations and
159 dnl all the fumbling with configure.in and acconfig.h
160 dnl were *way* more work than the feature itself :-(
162 dnl - Because a generic redirect template was needed for
163 dnl this, tinygif = 3 now uses the same.
165 dnl - Moved GIFs, and other static HTTP response templates
168 dnl - Some minor fixes
170 dnl - Removed some >400 CRs again (Jon, you really worked
173 dnl Revision 1.2 2001/05/20 01:21:20 jongfoster
174 dnl Version 2.9.4 checkin.
175 dnl - Merged popupfile and cookiefile, and added control over PCRS
176 dnl filtering, in new "permissionsfile".
177 dnl - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
178 dnl file error you now get a message box (in the Win32 GUI) rather
179 dnl than the program exiting with no explanation.
180 dnl - Made killpopup use the PCRS MIME-type checking and HTTP-header
182 dnl - Removed tabs from "config"
183 dnl - Moved duplicated url parsing code in "loaders.c" to a new funcition.
184 dnl - Bumped up version number.
