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