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