400 dnl Care is taken to avoid that pcre is dyn, while pcreposix
401 dnl is static, if both are used and that pcrs is static if
404 dnl The choice between pcre, gnu or no regex for actionsfile
405 dnl URL matching is now via
406 dnl --(enable|disable)-regex-matching[=(gnu|pcre|no)] with the

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