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