- * Revisions :
- * $Log: killpopup.c,v $
- * Revision 1.15 2002/03/24 13:25:43 swa
- * name change related issues
- *
- * Revision 1.14 2002/03/07 03:46:53 oes
- * Fixed compiler warnings etc
- *
- * Revision 1.13 2001/11/13 00:16:40 jongfoster
- * Replacing references to malloc.h with the standard stdlib.h
- * (See ANSI or K&R 2nd Ed)
- *
- * Revision 1.12 2001/10/25 03:40:48 david__schmidt
- * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
- * threads to call select() simultaneously. So, it's time to do a real, live,
- * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
- * (native). Both versions will work, but using __OS2__ offers multi-threading.
- *
- * Revision 1.11 2001/10/07 15:42:41 oes
- * filter_popups now gets a csp pointer so it can raise the new
- * CSP_FLAG_MODIFIED flag.
- *
- * Revision 1.10 2001/09/22 16:34:44 jongfoster
- * Removing unneeded #includes
- *
- * Revision 1.9 2001/07/31 14:44:22 oes
- * Deleted unused size parameter from filter_popups()
- *
- * Revision 1.8 2001/07/30 22:08:36 jongfoster
- * Tidying up #defines:
- * - All feature #defines are now of the form FEATURE_xxx
- * - Permanently turned off WIN_GUI_EDIT
- * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
- *
- * Revision 1.7 2001/07/20 19:29:25 haroon
- * - In v1.5 forgot to add that I implemented LOG_LEVEL_POPUPS in errlog.c,
- * errlog.h and killpopup.c. In that case, it is superfluous to have define for
- * POPUP_VERBOSE, so I removed the defines and logging is now done
- * via log_error(LOG_LEVEL_POPUPS, ....)
- *
- * Revision 1.6 2001/07/19 19:11:35 haroon
- * - Implemented Guy's idea of replacing window.open( with 1;''.concat(
- * - Implemented Guy's idea of replacing .resizeTo( with .scrollTo(

- * CRLF -> LF
- *
- * Revision 1.2 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".
- * - 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.
- * - Made killpopup use the PCRS MIME-type checking and HTTP-header
- * skipping.
- * - Removed tabs from "config"
- * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
- * - Bumped up version number.
- *
- * Revision 1.1.1.1 2001/05/15 13:58:58 oes
