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