46 * Revision 1.6 2001/06/03 19:12:38 oes
47 * deleted const struct interceptors
49 * Revision 1.5 2001/05/31 21:30:33 jongfoster
50 * Removed list code - it's now in list.[ch]
51 * Renamed "permission" to "action", and changed many features
52 * to use the actions file rather than the global config.
54 * Revision 1.4 2001/05/27 13:19:06 oes
55 * Patched Joergs solution for the content-length in.
57 * Revision 1.3 2001/05/26 13:39:32 jongfoster
58 * Only crunches Content-Length header if applying RE filtering.
59 * Without this fix, Microsoft Windows Update wouldn't work.
61 * Revision 1.2 2001/05/20 01:21:20 jongfoster
62 * Version 2.9.4 checkin.
63 * - Merged popupfile and cookiefile, and added control over PCRS
64 * filtering, in new "permissionsfile".
65 * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
66 * file error you now get a message box (in the Win32 GUI) rather
67 * than the program exiting with no explanation.
68 * - Made killpopup use the PCRS MIME-type checking and HTTP-header
70 * - Removed tabs from "config"
71 * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
72 * - Bumped up version number.
74 * Revision 1.1.1.1 2001/05/15 13:59:01 oes
75 * Initial import of version 2.9.3 source tree
