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