224 dnl Revision 1.7 2001/07/13 13:58:05 oes
225 dnl Completely reorganized the selection scheme for
226 dnl pcre, pcreposix, pcrs and gnu_regex:
228 dnl The presence of shared pcre, pcreposix or pcrs
229 dnl libraried is now autodetected. Additionally, the
230 dnl user can enforce using the built-in static variants
231 dnl by specifying --disable-dynamic-(pcre|pcrs).
232 dnl Care is taken to avoid that pcre is dyn, while pcreposix
233 dnl is static, if both are used and that pcrs is static if
236 dnl The choice between pcre, gnu or no regex for actionsfile
237 dnl URL matching is now via
238 dnl --(enable|disable)-regex-matching[=(gnu|pcre|no)] with the
239 dnl default being pcre.
241 dnl Revision 1.6 2001/06/29 21:56:40 oes
244 dnl Revision 1.5 2001/06/29 13:26:27 oes
245 dnl Introduced #define CODE_STATUS
247 dnl Revision 1.4 2001/05/29 09:50:24 jongfoster
248 dnl Unified blocklist/imagelist/permissionslist.
249 dnl File format is still under discussion, but the internal changes
250 dnl are (mostly) done.
252 dnl Also modified interceptor behaviour:
253 dnl - We now intercept all URLs beginning with one of the following
254 dnl prefixes (and *only* these prefixes):
256 dnl * http://ijbswa.sf.net/config/
257 dnl * http://ijbswa.sourceforge.net/config/
258 dnl - New interceptors "home page" - go to http://i.j.b/ to see it.
259 dnl - Internal changes so that intercepted and fast redirect pages
260 dnl are not replaced with an image.
261 dnl - Interceptors now have the option to send a binary page direct
262 dnl to the client. (i.e. ijb-send-banner uses this)
263 dnl - Implemented show-url-info interceptor. (Which is why I needed
264 dnl the above interceptors changes - a typical URL is
265 dnl "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
266 dnl The previous mechanism would not have intercepted that, and
267 dnl if it had been intercepted then it then it would have replaced
268 dnl it with an image.)
270 dnl Revision 1.3 2001/05/22 18:46:04 oes
272 dnl - Enabled filtering banners by size rather than URL
273 dnl by adding patterns that replace all standard banner
274 dnl sizes with the "Junkbuster" gif to the re_filterfile
276 dnl - Enabled filtering WebBugs by providing a pattern
277 dnl which kills all 1x1 images
279 dnl - Added support for PCRE_UNGREEDY behaviour to pcrs,
280 dnl which is selected by the (nonstandard and therefore
281 dnl capital) letter 'U' in the option string.
282 dnl It causes the quantifiers to be ungreedy by default.
283 dnl Appending a ? turns back to greedy (!).
285 dnl - Added a new interceptor ijb-send-banner, which
286 dnl sends back the "Junkbuster" gif. Without imagelist or
287 dnl MSIE detection support, or if tinygif = 1, or the
288 dnl URL isn't recognized as an imageurl, a lame HTML
289 dnl explanation is sent instead.
291 dnl - Added new feature, which permits blocking remote
292 dnl script redirects and firing back a local redirect
294 dnl The feature is conditionally compiled, i.e. it
295 dnl can be disabled with --disable-fast-redirects,
296 dnl plus it must be activated by a "fast-redirects"
297 dnl line in the config file, has its own log level
298 dnl and of course wants to be displayed by show-proxy-args
299 dnl Note: Boy, all the #ifdefs in 1001 locations and
300 dnl all the fumbling with configure.in and acconfig.h
301 dnl were *way* more work than the feature itself :-(
303 dnl - Because a generic redirect template was needed for
304 dnl this, tinygif = 3 now uses the same.
306 dnl - Moved GIFs, and other static HTTP response templates
309 dnl - Some minor fixes
311 dnl - Removed some >400 CRs again (Jon, you really worked
314 dnl Revision 1.2 2001/05/20 01:21:20 jongfoster
315 dnl Version 2.9.4 checkin.
316 dnl - Merged popupfile and cookiefile, and added control over PCRS
317 dnl filtering, in new "permissionsfile".
318 dnl - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
319 dnl file error you now get a message box (in the Win32 GUI) rather
320 dnl than the program exiting with no explanation.
321 dnl - Made killpopup use the PCRS MIME-type checking and HTTP-header
323 dnl - Removed tabs from "config"
324 dnl - Moved duplicated url parsing code in "loaders.c" to a new funcition.
325 dnl - Bumped up version number.
