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