+ * NO TIME LEFT
+ *
+ * Revision 1.7 2001/05/31 21:21:30 jongfoster
+ * Permissionsfile / actions file changes:
+ * - Changed "permission" to "action" throughout
+ * - changes to file format to allow string parameters
+ * - Moved helper functions to actions.c
+ *
+ * Revision 1.6 2001/05/29 09:50:24 jongfoster
+ * Unified blocklist/imagelist/permissionslist.
+ * File format is still under discussion, but the internal changes
+ * are (mostly) done.
+ *
+ * Also modified interceptor behaviour:
+ * - We now intercept all URLs beginning with one of the following
+ * prefixes (and *only* these prefixes):
+ * * http://i.j.b/
+ * * http://ijbswa.sf.net/config/
+ * * http://ijbswa.sourceforge.net/config/
+ * - New interceptors "home page" - go to http://i.j.b/ to see it.
+ * - Internal changes so that intercepted and fast redirect pages
+ * are not replaced with an image.
+ * - Interceptors now have the option to send a binary page direct
+ * to the client. (i.e. ijb-send-banner uses this)
+ * - Implemented show-url-info interceptor. (Which is why I needed
+ * the above interceptors changes - a typical URL is
+ * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
+ * The previous mechanism would not have intercepted that, and
+ * if it had been intercepted then it then it would have replaced
+ * it with an image.)
+ *
+ * Revision 1.5 2001/05/27 22:17:04 oes
+ *
+ * - re_process_buffer no longer writes the modified buffer
+ * to the client, which was very ugly. It now returns the
+ * buffer, which it is then written by chat.
+ *
+ * - content_length now adjusts the Content-Length: header
+ * for modified documents rather than crunch()ing it.
+ * (Length info in csp->content_length, which is 0 for
+ * unmodified documents)
+ *
+ * - For this to work, sed() is called twice when filtering.
+ *
+ * Revision 1.4 2001/05/26 15:26:15 jongfoster
+ * ACL feature now provides more security by immediately dropping
+ * connections from untrusted hosts.
+ *
+ * Revision 1.3 2001/05/22 18:46:04 oes
+ *
+ * - Enabled filtering banners by size rather than URL
+ * by adding patterns that replace all standard banner
+ * sizes with the "Junkbuster" gif to the re_filterfile
+ *
+ * - Enabled filtering WebBugs by providing a pattern
+ * which kills all 1x1 images
+ *
+ * - Added support for PCRE_UNGREEDY behaviour to pcrs,
+ * which is selected by the (nonstandard and therefore
+ * capital) letter 'U' in the option string.
+ * It causes the quantifiers to be ungreedy by default.
+ * Appending a ? turns back to greedy (!).
+ *
+ * - Added a new interceptor ijb-send-banner, which
+ * sends back the "Junkbuster" gif. Without imagelist or
+ * MSIE detection support, or if tinygif = 1, or the
+ * URL isn't recognized as an imageurl, a lame HTML
+ * explanation is sent instead.
+ *
+ * - Added new feature, which permits blocking remote
+ * script redirects and firing back a local redirect
+ * to the browser.
+ * The feature is conditionally compiled, i.e. it
+ * can be disabled with --disable-fast-redirects,
+ * plus it must be activated by a "fast-redirects"
+ * line in the config file, has its own log level
+ * and of course wants to be displayed by show-proxy-args
+ * Note: Boy, all the #ifdefs in 1001 locations and
+ * all the fumbling with configure.in and acconfig.h
+ * were *way* more work than the feature itself :-(
+ *
+ * - Because a generic redirect template was needed for
+ * this, tinygif = 3 now uses the same.
+ *
+ * - Moved GIFs, and other static HTTP response templates
+ * to project.h
+ *
+ * - Some minor fixes
+ *
+ * - Removed some >400 CRs again (Jon, you really worked
+ * a lot! ;-)
+ *
+ * Revision 1.2 2001/05/20 01:21:20 jongfoster
+ * Version 2.9.4 checkin.
+ * - Merged popupfile and cookiefile, and added control over PCRS
+ * filtering, in new "permissionsfile".
+ * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
+ * file error you now get a message box (in the Win32 GUI) rather
+ * than the program exiting with no explanation.
+ * - Made killpopup use the PCRS MIME-type checking and HTTP-header
+ * skipping.
+ * - Removed tabs from "config"
+ * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
+ * - Bumped up version number.
+ *
+ * Revision 1.1.1.1 2001/05/15 13:58:52 oes
+ * Initial import of version 2.9.3 source tree
+ *
