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