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