31 dnl Revision 1.11 2001/07/21 18:00:07 jongfoster
32 dnl Bumping version number to 2.9.7
34 dnl Revision 1.10 2001/07/18 17:25:04 oes
37 dnl Revision 1.9 2001/07/15 19:45:13 jongfoster
38 dnl Added support for linking with POSIX threads library
40 dnl Revision 1.8 2001/07/15 17:54:29 jongfoster
41 dnl Renaming #define STATIC to STATIC_PCRE
42 dnl Adding new #define FEATURE_PTHREAD that will be used to enable
43 dnl POSIX threads support.
45 dnl Revision 1.7 2001/07/13 13:58:05 oes
46 dnl Completely reorganized the selection scheme for
47 dnl pcre, pcreposix, pcrs and gnu_regex:
49 dnl The presence of shared pcre, pcreposix or pcrs
50 dnl libraried is now autodetected. Additionally, the
51 dnl user can enforce using the built-in static variants
52 dnl by specifying --disable-dynamic-(pcre|pcrs).
53 dnl Care is taken to avoid that pcre is dyn, while pcreposix
54 dnl is static, if both are used and that pcrs is static if
57 dnl The choice between pcre, gnu or no regex for actionsfile
58 dnl URL matching is now via
59 dnl --(enable|disable)-regex-matching[=(gnu|pcre|no)] with the
60 dnl default being pcre.
62 dnl Revision 1.6 2001/06/29 21:56:40 oes
65 dnl Revision 1.5 2001/06/29 13:26:27 oes
66 dnl Introduced #define CODE_STATUS
68 dnl Revision 1.4 2001/05/29 09:50:24 jongfoster
69 dnl Unified blocklist/imagelist/permissionslist.
70 dnl File format is still under discussion, but the internal changes
71 dnl are (mostly) done.
73 dnl Also modified interceptor behaviour:
74 dnl - We now intercept all URLs beginning with one of the following
75 dnl prefixes (and *only* these prefixes):
77 dnl * http://ijbswa.sf.net/config/
78 dnl * http://ijbswa.sourceforge.net/config/
79 dnl - New interceptors "home page" - go to http://i.j.b/ to see it.
80 dnl - Internal changes so that intercepted and fast redirect pages
81 dnl are not replaced with an image.
82 dnl - Interceptors now have the option to send a binary page direct
83 dnl to the client. (i.e. ijb-send-banner uses this)
84 dnl - Implemented show-url-info interceptor. (Which is why I needed
85 dnl the above interceptors changes - a typical URL is
86 dnl "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
87 dnl The previous mechanism would not have intercepted that, and
88 dnl if it had been intercepted then it then it would have replaced
89 dnl it with an image.)
91 dnl Revision 1.3 2001/05/22 18:46:04 oes
93 dnl - Enabled filtering banners by size rather than URL
94 dnl by adding patterns that replace all standard banner
95 dnl sizes with the "Junkbuster" gif to the re_filterfile
97 dnl - Enabled filtering WebBugs by providing a pattern
98 dnl which kills all 1x1 images
100 dnl - Added support for PCRE_UNGREEDY behaviour to pcrs,
101 dnl which is selected by the (nonstandard and therefore
102 dnl capital) letter 'U' in the option string.
103 dnl It causes the quantifiers to be ungreedy by default.
104 dnl Appending a ? turns back to greedy (!).
106 dnl - Added a new interceptor ijb-send-banner, which
107 dnl sends back the "Junkbuster" gif. Without imagelist or
108 dnl MSIE detection support, or if tinygif = 1, or the
109 dnl URL isn't recognized as an imageurl, a lame HTML
110 dnl explanation is sent instead.
112 dnl - Added new feature, which permits blocking remote
113 dnl script redirects and firing back a local redirect
115 dnl The feature is conditionally compiled, i.e. it
116 dnl can be disabled with --disable-fast-redirects,
117 dnl plus it must be activated by a "fast-redirects"
118 dnl line in the config file, has its own log level
119 dnl and of course wants to be displayed by show-proxy-args
120 dnl Note: Boy, all the #ifdefs in 1001 locations and
121 dnl all the fumbling with configure.in and acconfig.h
122 dnl were *way* more work than the feature itself :-(
124 dnl - Because a generic redirect template was needed for
125 dnl this, tinygif = 3 now uses the same.
127 dnl - Moved GIFs, and other static HTTP response templates
130 dnl - Some minor fixes
132 dnl - Removed some >400 CRs again (Jon, you really worked
135 dnl Revision 1.2 2001/05/20 01:21:20 jongfoster
136 dnl Version 2.9.4 checkin.
137 dnl - Merged popupfile and cookiefile, and added control over PCRS
138 dnl filtering, in new "permissionsfile".
139 dnl - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
140 dnl file error you now get a message box (in the Win32 GUI) rather
141 dnl than the program exiting with no explanation.
142 dnl - Made killpopup use the PCRS MIME-type checking and HTTP-header
144 dnl - Removed tabs from "config"
145 dnl - Moved duplicated url parsing code in "loaders.c" to a new funcition.
146 dnl - Bumped up version number.
