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