46 * Revision 1.3 2001/05/26 13:39:32 jongfoster
47 * Only crunches Content-Length header if applying RE filtering.
48 * Without this fix, Microsoft Windows Update wouldn't work.
50 * Revision 1.2 2001/05/20 01:21:20 jongfoster
51 * Version 2.9.4 checkin.
52 * - Merged popupfile and cookiefile, and added control over PCRS
53 * filtering, in new "permissionsfile".
54 * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
55 * file error you now get a message box (in the Win32 GUI) rather
56 * than the program exiting with no explanation.
57 * - Made killpopup use the PCRS MIME-type checking and HTTP-header
59 * - Removed tabs from "config"
60 * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
61 * - Bumped up version number.
63 * Revision 1.1.1.1 2001/05/15 13:59:01 oes
64 * Initial import of version 2.9.3 source tree
