+ * Revision 1.13 2001/06/01 20:05:36 jongfoster
+ * Support for +image-blocker{}: added ACTION_IMAGE_BLOCKER
+ * constant, and removed csp->tinygif.
+ *
+ * Revision 1.12 2001/06/01 18:49:17 jongfoster
+ * Replaced "list_share" with "list" - the tiny memory gain was not
+ * worth the extra complexity.
+ *
+ * Revision 1.11 2001/06/01 10:32:47 oes
+ * Added constants for anchoring selection bitmap
+ *
+ * Revision 1.10 2001/05/31 21:33:53 jongfoster
+ * Changes for new actions file, replacing permissionsfile
+ * and parts of the config file. Also added support for
+ * list_shared.
+ *
+ * Revision 1.9 2001/05/31 17:32:31 oes
+ *
+ * - Enhanced domain part globbing with infix and prefix asterisk
+ * matching and optional unanchored operation
+ *
+ * Revision 1.8 2001/05/29 20:09:15 joergs
+ * HTTP_REDIRECT_TEMPLATE fixed.
+ *
+ * Revision 1.7 2001/05/29 09:50:24 jongfoster
+ * Unified blocklist/imagelist/actionslist.
+ * File format is still under discussion, but the internal changes
+ * are (mostly) done.
+ *
+ * Also modified interceptor behaviour:
+ * - We now intercept all URLs beginning with one of the following
+ * prefixes (and *only* these prefixes):
+ * * http://i.j.b/
+ * * http://ijbswa.sf.net/config/
+ * * http://ijbswa.sourceforge.net/config/
+ * - New interceptors "home page" - go to http://i.j.b/ to see it.
+ * - Internal changes so that intercepted and fast redirect pages
+ * are not replaced with an image.
+ * - Interceptors now have the option to send a binary page direct
+ * to the client. (i.e. ijb-send-banner uses this)
+ * - Implemented show-url-info interceptor. (Which is why I needed
+ * the above interceptors changes - a typical URL is
+ * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
+ * The previous mechanism would not have intercepted that, and
+ * if it had been intercepted then it then it would have replaced
+ * it with an image.)
+ *
* Revision 1.6 2001/05/27 22:17:04 oes
*
* - re_process_buffer no longer writes the modified buffer
* Revision 1.3 2001/05/20 01:21:20 jongfoster
* Version 2.9.4 checkin.
* - Merged popupfile and cookiefile, and added control over PCRS
- * filtering, in new "permissionsfile".
+ * filtering, in new "actionsfile".
* - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
* file error you now get a message box (in the Win32 GUI) rather
* than the program exiting with no explanation.
