+dnl Revision 1.9 2001/07/15 19:45:13 jongfoster
+dnl Added support for linking with POSIX threads library
+dnl
+dnl Revision 1.8 2001/07/15 17:54:29 jongfoster
+dnl Renaming #define STATIC to STATIC_PCRE
+dnl Adding new #define FEATURE_PTHREAD that will be used to enable
+dnl POSIX threads support.
+dnl
+dnl Revision 1.7 2001/07/13 13:58:05 oes
+dnl Completely reorganized the selection scheme for
+dnl pcre, pcreposix, pcrs and gnu_regex:
+dnl
+dnl The presence of shared pcre, pcreposix or pcrs
+dnl libraried is now autodetected. Additionally, the
+dnl user can enforce using the built-in static variants
+dnl by specifying --disable-dynamic-(pcre|pcrs).
+dnl Care is taken to avoid that pcre is dyn, while pcreposix
+dnl is static, if both are used and that pcrs is static if
+dnl pcrs is.
+dnl
+dnl The choice between pcre, gnu or no regex for actionsfile
+dnl URL matching is now via
+dnl --(enable|disable)-regex-matching[=(gnu|pcre|no)] with the
+dnl default being pcre.
+dnl
+dnl Revision 1.6 2001/06/29 21:56:40 oes
+dnl Version -> 2.9.5
+dnl
+dnl Revision 1.5 2001/06/29 13:26:27 oes
+dnl Introduced #define CODE_STATUS
+dnl
+dnl Revision 1.4 2001/05/29 09:50:24 jongfoster
+dnl Unified blocklist/imagelist/permissionslist.
+dnl File format is still under discussion, but the internal changes
+dnl are (mostly) done.
+dnl
+dnl Also modified interceptor behaviour:
+dnl - We now intercept all URLs beginning with one of the following
+dnl prefixes (and *only* these prefixes):
+dnl * http://i.j.b/
+dnl * http://ijbswa.sf.net/config/
+dnl * http://ijbswa.sourceforge.net/config/
+dnl - New interceptors "home page" - go to http://i.j.b/ to see it.
+dnl - Internal changes so that intercepted and fast redirect pages
+dnl are not replaced with an image.
+dnl - Interceptors now have the option to send a binary page direct
+dnl to the client. (i.e. ijb-send-banner uses this)
+dnl - Implemented show-url-info interceptor. (Which is why I needed
+dnl the above interceptors changes - a typical URL is
+dnl "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
+dnl The previous mechanism would not have intercepted that, and
+dnl if it had been intercepted then it then it would have replaced
+dnl it with an image.)
+dnl
+dnl Revision 1.3 2001/05/22 18:46:04 oes
+dnl
+dnl - Enabled filtering banners by size rather than URL
+dnl by adding patterns that replace all standard banner
+dnl sizes with the "Junkbuster" gif to the re_filterfile
+dnl
+dnl - Enabled filtering WebBugs by providing a pattern
+dnl which kills all 1x1 images
+dnl
+dnl - Added support for PCRE_UNGREEDY behaviour to pcrs,
+dnl which is selected by the (nonstandard and therefore
+dnl capital) letter 'U' in the option string.
+dnl It causes the quantifiers to be ungreedy by default.
+dnl Appending a ? turns back to greedy (!).
+dnl
+dnl - Added a new interceptor ijb-send-banner, which
+dnl sends back the "Junkbuster" gif. Without imagelist or
+dnl MSIE detection support, or if tinygif = 1, or the
+dnl URL isn't recognized as an imageurl, a lame HTML
+dnl explanation is sent instead.
+dnl
+dnl - Added new feature, which permits blocking remote
+dnl script redirects and firing back a local redirect
+dnl to the browser.
+dnl The feature is conditionally compiled, i.e. it
+dnl can be disabled with --disable-fast-redirects,
+dnl plus it must be activated by a "fast-redirects"
+dnl line in the config file, has its own log level
+dnl and of course wants to be displayed by show-proxy-args
+dnl Note: Boy, all the #ifdefs in 1001 locations and
+dnl all the fumbling with configure.in and acconfig.h
+dnl were *way* more work than the feature itself :-(
+dnl
+dnl - Because a generic redirect template was needed for
+dnl this, tinygif = 3 now uses the same.
+dnl
+dnl - Moved GIFs, and other static HTTP response templates
+dnl to project.h
+dnl
+dnl - Some minor fixes
+dnl
+dnl - Removed some >400 CRs again (Jon, you really worked
+dnl a lot! ;-)
