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