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