170 dnl Fixing Solaris build (I hope) and tidying up #defines:
171 dnl - All feature #defines are now of the form FEATURE_xxx

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