454 dnl - Implemented show-url-info interceptor. (Which is why I needed
455 dnl the above interceptors changes - a typical URL is
456 dnl "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
457 dnl The previous mechanism would not have intercepted that, and
458 dnl if it had been intercepted then it then it would have replaced
459 dnl it with an image.)
461 dnl Revision 1.3 2001/05/22 18:46:04 oes
463 dnl - Enabled filtering banners by size rather than URL
464 dnl by adding patterns that replace all standard banner
465 dnl sizes with the "Junkbuster" gif to the re_filterfile
467 dnl - Enabled filtering WebBugs by providing a pattern
468 dnl which kills all 1x1 images
470 dnl - Added support for PCRE_UNGREEDY behaviour to pcrs,
471 dnl which is selected by the (nonstandard and therefore
472 dnl capital) letter 'U' in the option string.
473 dnl It causes the quantifiers to be ungreedy by default.
474 dnl Appending a ? turns back to greedy (!).
476 dnl - Added a new interceptor ijb-send-banner, which
477 dnl sends back the "Junkbuster" gif. Without imagelist or
478 dnl MSIE detection support, or if tinygif = 1, or the
479 dnl URL isn't recognized as an imageurl, a lame HTML
480 dnl explanation is sent instead.
482 dnl - Added new feature, which permits blocking remote
483 dnl script redirects and firing back a local redirect
485 dnl The feature is conditionally compiled, i.e. it
486 dnl can be disabled with --disable-fast-redirects,
487 dnl plus it must be activated by a "fast-redirects"
488 dnl line in the config file, has its own log level
489 dnl and of course wants to be displayed by show-proxy-args
490 dnl Note: Boy, all the #ifdefs in 1001 locations and
491 dnl all the fumbling with configure.in and acconfig.h
492 dnl were *way* more work than the feature itself :-(
494 dnl - Because a generic redirect template was needed for
495 dnl this, tinygif = 3 now uses the same.
497 dnl - Moved GIFs, and other static HTTP response templates
500 dnl - Some minor fixes
502 dnl - Removed some >400 CRs again (Jon, you really worked
505 dnl Revision 1.2 2001/05/20 01:21:20 jongfoster
506 dnl Version 2.9.4 checkin.
507 dnl - Merged popupfile and cookiefile, and added control over PCRS
508 dnl filtering, in new "permissionsfile".
509 dnl - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
510 dnl file error you now get a message box (in the Win32 GUI) rather
511 dnl than the program exiting with no explanation.
512 dnl - Made killpopup use the PCRS MIME-type checking and HTTP-header
514 dnl - Removed tabs from "config"
515 dnl - Moved duplicated url parsing code in "loaders.c" to a new funcition.
516 dnl - Bumped up version number.
