393 dnl The presence of shared pcre, pcreposix or pcrs
394 dnl libraried is now autodetected. Additionally, the

396 dnl by specifying --disable-dynamic-(pcre|pcrs).
397 dnl Care is taken to avoid that pcre is dyn, while pcreposix
398 dnl is static, if both are used and that pcrs is static if
401 dnl The choice between pcre, gnu or no regex for actionsfile
402 dnl URL matching is now via
403 dnl --(enable|disable)-regex-matching[=(gnu|pcre|no)] with the

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