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