395 dnl The choice between pcre, gnu or no regex for actionsfile

397 dnl --(enable|disable)-regex-matching[=(gnu|pcre|no)] with the

400 dnl Revision 1.6 2001/06/29 21:56:40 oes
403 dnl Revision 1.5 2001/06/29 13:26:27 oes
404 dnl Introduced #define CODE_STATUS
406 dnl Revision 1.4 2001/05/29 09:50:24 jongfoster
407 dnl Unified blocklist/imagelist/permissionslist.
408 dnl File format is still under discussion, but the internal changes
409 dnl are (mostly) done.
411 dnl Also modified interceptor behaviour:
412 dnl - We now intercept all URLs beginning with one of the following
413 dnl prefixes (and *only* these prefixes):
415 dnl * http://ijbswa.sf.net/config/
416 dnl * http://ijbswa.sourceforge.net/config/
417 dnl - New interceptors "home page" - go to http://i.j.b/ to see it.
418 dnl - Internal changes so that intercepted and fast redirect pages
419 dnl are not replaced with an image.
420 dnl - Interceptors now have the option to send a binary page direct
421 dnl to the client. (i.e. ijb-send-banner uses this)
422 dnl - Implemented show-url-info interceptor. (Which is why I needed
423 dnl the above interceptors changes - a typical URL is
424 dnl "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
425 dnl The previous mechanism would not have intercepted that, and
426 dnl if it had been intercepted then it then it would have replaced
427 dnl it with an image.)
429 dnl Revision 1.3 2001/05/22 18:46:04 oes
431 dnl - Enabled filtering banners by size rather than URL
432 dnl by adding patterns that replace all standard banner
433 dnl sizes with the "Junkbuster" gif to the re_filterfile
435 dnl - Enabled filtering WebBugs by providing a pattern
436 dnl which kills all 1x1 images
438 dnl - Added support for PCRE_UNGREEDY behaviour to pcrs,
439 dnl which is selected by the (nonstandard and therefore
440 dnl capital) letter 'U' in the option string.
441 dnl It causes the quantifiers to be ungreedy by default.
442 dnl Appending a ? turns back to greedy (!).
444 dnl - Added a new interceptor ijb-send-banner, which
445 dnl sends back the "Junkbuster" gif. Without imagelist or
446 dnl MSIE detection support, or if tinygif = 1, or the
447 dnl URL isn't recognized as an imageurl, a lame HTML
448 dnl explanation is sent instead.
450 dnl - Added new feature, which permits blocking remote
451 dnl script redirects and firing back a local redirect
453 dnl The feature is conditionally compiled, i.e. it
454 dnl can be disabled with --disable-fast-redirects,
455 dnl plus it must be activated by a "fast-redirects"
456 dnl line in the config file, has its own log level
457 dnl and of course wants to be displayed by show-proxy-args
458 dnl Note: Boy, all the #ifdefs in 1001 locations and
459 dnl all the fumbling with configure.in and acconfig.h
460 dnl were *way* more work than the feature itself :-(
462 dnl - Because a generic redirect template was needed for
