34 * $Log: killpopup.c,v $
35 * Revision 1.11 2001/10/07 15:42:41 oes
36 * filter_popups now gets a csp pointer so it can raise the new
37 * CSP_FLAG_MODIFIED flag.
39 * Revision 1.10 2001/09/22 16:34:44 jongfoster
40 * Removing unneeded #includes
42 * Revision 1.9 2001/07/31 14:44:22 oes
43 * Deleted unused size parameter from filter_popups()
45 * Revision 1.8 2001/07/30 22:08:36 jongfoster
46 * Tidying up #defines:
47 * - All feature #defines are now of the form FEATURE_xxx
48 * - Permanently turned off WIN_GUI_EDIT
49 * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
51 * Revision 1.7 2001/07/20 19:29:25 haroon
52 * - In v1.5 forgot to add that I implemented LOG_LEVEL_POPUPS in errlog.c,
53 * errlog.h and killpopup.c. In that case, it is superfluous to have define for
54 * POPUP_VERBOSE, so I removed the defines and logging is now done
55 * via log_error(LOG_LEVEL_POPUPS, ....)
57 * Revision 1.6 2001/07/19 19:11:35 haroon
58 * - Implemented Guy's idea of replacing window.open( with 1;''.concat(
59 * - Implemented Guy's idea of replacing .resizeTo( with .scrollTo(
61 * Revision 1.5 2001/07/18 15:02:52 haroon
62 * improved nuking of window.open
64 * Revision 1.4 2001/06/29 13:29:55 oes
65 * Added FIXMEs (and didn't repair, hehe)
67 * Revision 1.3 2001/05/22 18:56:28 oes
70 * Revision 1.2 2001/05/20 01:21:20 jongfoster
71 * Version 2.9.4 checkin.
72 * - Merged popupfile and cookiefile, and added control over PCRS
73 * filtering, in new "permissionsfile".
74 * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
75 * file error you now get a message box (in the Win32 GUI) rather
76 * than the program exiting with no explanation.
77 * - Made killpopup use the PCRS MIME-type checking and HTTP-header
79 * - Removed tabs from "config"
80 * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
81 * - Bumped up version number.
83 * Revision 1.1.1.1 2001/05/15 13:58:58 oes
84 * Initial import of version 2.9.3 source tree
