443 dnl Bumping version number to 2.9.7
445 dnl Revision 1.10 2001/07/18 17:25:04 oes
448 dnl Revision 1.9 2001/07/15 19:45:13 jongfoster
449 dnl Added support for linking with POSIX threads library
451 dnl Revision 1.8 2001/07/15 17:54:29 jongfoster
452 dnl Renaming #define STATIC to STATIC_PCRE
453 dnl Adding new #define FEATURE_PTHREAD that will be used to enable
454 dnl POSIX threads support.
456 dnl Revision 1.7 2001/07/13 13:58:05 oes
457 dnl Completely reorganized the selection scheme for
458 dnl pcre, pcreposix, pcrs and gnu_regex:
460 dnl The presence of shared pcre, pcreposix or pcrs
461 dnl libraried is now autodetected. Additionally, the
462 dnl user can enforce using the built-in static variants
463 dnl by specifying --disable-dynamic-(pcre|pcrs).
464 dnl Care is taken to avoid that pcre is dyn, while pcreposix
465 dnl is static, if both are used and that pcrs is static if
468 dnl The choice between pcre, gnu or no regex for actionsfile
469 dnl URL matching is now via
470 dnl --(enable|disable)-regex-matching[=(gnu|pcre|no)] with the
471 dnl default being pcre.
473 dnl Revision 1.6 2001/06/29 21:56:40 oes
476 dnl Revision 1.5 2001/06/29 13:26:27 oes
477 dnl Introduced #define CODE_STATUS
479 dnl Revision 1.4 2001/05/29 09:50:24 jongfoster
480 dnl Unified blocklist/imagelist/permissionslist.
481 dnl File format is still under discussion, but the internal changes
482 dnl are (mostly) done.
484 dnl Also modified interceptor behaviour:
485 dnl - We now intercept all URLs beginning with one of the following
486 dnl prefixes (and *only* these prefixes):
488 dnl * http://ijbswa.sf.net/config/
489 dnl * http://ijbswa.sourceforge.net/config/
490 dnl - New interceptors "home page" - go to http://i.j.b/ to see it.
491 dnl - Internal changes so that intercepted and fast redirect pages
492 dnl are not replaced with an image.
493 dnl - Interceptors now have the option to send a binary page direct
494 dnl to the client. (i.e. ijb-send-banner uses this)
495 dnl - Implemented show-url-info interceptor. (Which is why I needed
496 dnl the above interceptors changes - a typical URL is
497 dnl "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
498 dnl The previous mechanism would not have intercepted that, and
499 dnl if it had been intercepted then it then it would have replaced
500 dnl it with an image.)
502 dnl Revision 1.3 2001/05/22 18:46:04 oes
504 dnl - Enabled filtering banners by size rather than URL
505 dnl by adding patterns that replace all standard banner
506 dnl sizes with the "Junkbuster" gif to the re_filterfile
508 dnl - Enabled filtering WebBugs by providing a pattern
509 dnl which kills all 1x1 images
511 dnl - Added support for PCRE_UNGREEDY behaviour to pcrs,
512 dnl which is selected by the (nonstandard and therefore
513 dnl capital) letter 'U' in the option string.
514 dnl It causes the quantifiers to be ungreedy by default.
515 dnl Appending a ? turns back to greedy (!).
517 dnl - Added a new interceptor ijb-send-banner, which
518 dnl sends back the "Junkbuster" gif. Without imagelist or
519 dnl MSIE detection support, or if tinygif = 1, or the
520 dnl URL isn't recognized as an imageurl, a lame HTML
521 dnl explanation is sent instead.
523 dnl - Added new feature, which permits blocking remote
524 dnl script redirects and firing back a local redirect
526 dnl The feature is conditionally compiled, i.e. it
527 dnl can be disabled with --disable-fast-redirects,
528 dnl plus it must be activated by a "fast-redirects"
529 dnl line in the config file, has its own log level
530 dnl and of course wants to be displayed by show-proxy-args
531 dnl Note: Boy, all the #ifdefs in 1001 locations and
532 dnl all the fumbling with configure.in and acconfig.h
533 dnl were *way* more work than the feature itself :-(
535 dnl - Because a generic redirect template was needed for
536 dnl this, tinygif = 3 now uses the same.
538 dnl - Moved GIFs, and other static HTTP response templates
541 dnl - Some minor fixes
543 dnl - Removed some >400 CRs again (Jon, you really worked
546 dnl Revision 1.2 2001/05/20 01:21:20 jongfoster
547 dnl Version 2.9.4 checkin.
548 dnl - Merged popupfile and cookiefile, and added control over PCRS
549 dnl filtering, in new "permissionsfile".
550 dnl - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
551 dnl file error you now get a message box (in the Win32 GUI) rather
552 dnl than the program exiting with no explanation.
553 dnl - Made killpopup use the PCRS MIME-type checking and HTTP-header
555 dnl - Removed tabs from "config"
556 dnl - Moved duplicated url parsing code in "loaders.c" to a new funcition.
557 dnl - Bumped up version number.
