424 dnl Revision 1.4 2001/05/29 09:50:24 jongfoster
425 dnl Unified blocklist/imagelist/permissionslist.
426 dnl File format is still under discussion, but the internal changes
427 dnl are (mostly) done.
429 dnl Also modified interceptor behaviour:
430 dnl - We now intercept all URLs beginning with one of the following
431 dnl prefixes (and *only* these prefixes):
433 dnl * http://ijbswa.sf.net/config/
434 dnl * http://ijbswa.sourceforge.net/config/
435 dnl - New interceptors "home page" - go to http://i.j.b/ to see it.
436 dnl - Internal changes so that intercepted and fast redirect pages
437 dnl are not replaced with an image.
438 dnl - Interceptors now have the option to send a binary page direct
439 dnl to the client. (i.e. ijb-send-banner uses this)
440 dnl - Implemented show-url-info interceptor. (Which is why I needed
441 dnl the above interceptors changes - a typical URL is
442 dnl "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
443 dnl The previous mechanism would not have intercepted that, and
444 dnl if it had been intercepted then it then it would have replaced
445 dnl it with an image.)
447 dnl Revision 1.3 2001/05/22 18:46:04 oes
449 dnl - Enabled filtering banners by size rather than URL
450 dnl by adding patterns that replace all standard banner
451 dnl sizes with the "Junkbuster" gif to the re_filterfile
453 dnl - Enabled filtering WebBugs by providing a pattern
454 dnl which kills all 1x1 images
456 dnl - Added support for PCRE_UNGREEDY behaviour to pcrs,
457 dnl which is selected by the (nonstandard and therefore
458 dnl capital) letter 'U' in the option string.

460 dnl Appending a ? turns back to greedy (!).
462 dnl - Added a new interceptor ijb-send-banner, which
463 dnl sends back the "Junkbuster" gif. Without imagelist or
464 dnl MSIE detection support, or if tinygif = 1, or the
465 dnl URL isn't recognized as an imageurl, a lame HTML
466 dnl explanation is sent instead.
468 dnl - Added new feature, which permits blocking remote
469 dnl script redirects and firing back a local redirect
471 dnl The feature is conditionally compiled, i.e. it
472 dnl can be disabled with --disable-fast-redirects,

480 dnl - Because a generic redirect template was needed for
481 dnl this, tinygif = 3 now uses the same.

493 dnl - Merged popupfile and cookiefile, and added control over PCRS

495 dnl - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
496 dnl file error you now get a message box (in the Win32 GUI) rather
