328 dnl The presence of shared pcre, pcreposix or pcrs
329 dnl libraried is now autodetected. Additionally, the
330 dnl user can enforce using the built-in static variants
331 dnl by specifying --disable-dynamic-(pcre|pcrs).
332 dnl Care is taken to avoid that pcre is dyn, while pcreposix
333 dnl is static, if both are used and that pcrs is static if
336 dnl The choice between pcre, gnu or no regex for actionsfile
337 dnl URL matching is now via
338 dnl --(enable|disable)-regex-matching[=(gnu|pcre|no)] with the
339 dnl default being pcre.
341 dnl Revision 1.6 2001/06/29 21:56:40 oes
344 dnl Revision 1.5 2001/06/29 13:26:27 oes
345 dnl Introduced #define CODE_STATUS
347 dnl Revision 1.4 2001/05/29 09:50:24 jongfoster
348 dnl Unified blocklist/imagelist/permissionslist.
349 dnl File format is still under discussion, but the internal changes
350 dnl are (mostly) done.
352 dnl Also modified interceptor behaviour:
353 dnl - We now intercept all URLs beginning with one of the following
354 dnl prefixes (and *only* these prefixes):
356 dnl * http://ijbswa.sf.net/config/
357 dnl * http://ijbswa.sourceforge.net/config/
358 dnl - New interceptors "home page" - go to http://i.j.b/ to see it.
359 dnl - Internal changes so that intercepted and fast redirect pages
360 dnl are not replaced with an image.
361 dnl - Interceptors now have the option to send a binary page direct
362 dnl to the client. (i.e. ijb-send-banner uses this)
363 dnl - Implemented show-url-info interceptor. (Which is why I needed
364 dnl the above interceptors changes - a typical URL is
365 dnl "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
366 dnl The previous mechanism would not have intercepted that, and
367 dnl if it had been intercepted then it then it would have replaced
368 dnl it with an image.)
370 dnl Revision 1.3 2001/05/22 18:46:04 oes
372 dnl - Enabled filtering banners by size rather than URL
373 dnl by adding patterns that replace all standard banner
374 dnl sizes with the "Junkbuster" gif to the re_filterfile
376 dnl - Enabled filtering WebBugs by providing a pattern
377 dnl which kills all 1x1 images
379 dnl - Added support for PCRE_UNGREEDY behaviour to pcrs,
380 dnl which is selected by the (nonstandard and therefore
381 dnl capital) letter 'U' in the option string.
382 dnl It causes the quantifiers to be ungreedy by default.
383 dnl Appending a ? turns back to greedy (!).
385 dnl - Added a new interceptor ijb-send-banner, which
386 dnl sends back the "Junkbuster" gif. Without imagelist or
387 dnl MSIE detection support, or if tinygif = 1, or the
388 dnl URL isn't recognized as an imageurl, a lame HTML
389 dnl explanation is sent instead.
391 dnl - Added new feature, which permits blocking remote
392 dnl script redirects and firing back a local redirect
394 dnl The feature is conditionally compiled, i.e. it
395 dnl can be disabled with --disable-fast-redirects,
396 dnl plus it must be activated by a "fast-redirects"
397 dnl line in the config file, has its own log level
398 dnl and of course wants to be displayed by show-proxy-args
399 dnl Note: Boy, all the #ifdefs in 1001 locations and
400 dnl all the fumbling with configure.in and acconfig.h
401 dnl were *way* more work than the feature itself :-(
403 dnl - Because a generic redirect template was needed for
404 dnl this, tinygif = 3 now uses the same.
406 dnl - Moved GIFs, and other static HTTP response templates
409 dnl - Some minor fixes
411 dnl - Removed some >400 CRs again (Jon, you really worked
414 dnl Revision 1.2 2001/05/20 01:21:20 jongfoster
415 dnl Version 2.9.4 checkin.
416 dnl - Merged popupfile and cookiefile, and added control over PCRS
417 dnl filtering, in new "permissionsfile".
418 dnl - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
419 dnl file error you now get a message box (in the Win32 GUI) rather
420 dnl than the program exiting with no explanation.
421 dnl - Made killpopup use the PCRS MIME-type checking and HTTP-header
423 dnl - Removed tabs from "config"
424 dnl - Moved duplicated url parsing code in "loaders.c" to a new funcition.
425 dnl - Bumped up version number.
