+ * Indentation, CRLF->LF, Tab-> Space
+ *
+ * Revision 1.17 2001/06/29 13:31:51 oes
+ * Various adaptions
+ *
+ * Revision 1.16 2001/06/09 10:55:28 jongfoster
+ * Changing BUFSIZ ==> BUFFER_SIZE
+ *
+ * Revision 1.15 2001/06/07 23:14:14 jongfoster
+ * Removing ACL and forward file loaders - these
+ * files have been merged into the config file.
+ * Cosmetic: Moving unloader funcs next to their
+ * respective loader funcs
+ *
+ * Revision 1.14 2001/06/01 03:27:04 oes
+ * Fixed line continuation problem
+ *
+ * Revision 1.13 2001/05/31 21:28:49 jongfoster
+ * Removed all permissionsfile code - it's now called the actions
+ * file, and (almost) all the code is in actions.c
+ *
+ * Revision 1.12 2001/05/31 17:32:31 oes
+ *
+ * - Enhanced domain part globbing with infix and prefix asterisk
+ * matching and optional unanchored operation
+ *
+ * Revision 1.11 2001/05/29 23:25:24 oes
+ *
+ * - load_config_line() and load_permissions_file() now use chomp()
+ *
+ * Revision 1.10 2001/05/29 09:50:24 jongfoster
+ * Unified blocklist/imagelist/permissionslist.
+ * 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 1.9 2001/05/26 17:12:07 jongfoster
+ * Fatal errors loading configuration files now give better error messages.
+ *
+ * Revision 1.8 2001/05/26 00:55:20 jongfoster
+ * Removing duplicated code. load_forwardfile() now uses create_url_spec()
+ *
+ * Revision 1.7 2001/05/26 00:28:36 jongfoster
+ * Automatic reloading of config file.
+ * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
+ * Most of the global variables have been moved to a new
+ * struct configuration_spec, accessed through csp->config->globalname
+ * Most of the globals remaining are used by the Win32 GUI.
+ *
+ * Revision 1.6 2001/05/23 12:27:33 oes
+ *
+ * Fixed ugly indentation of my last changes
+ *
+ * Revision 1.5 2001/05/23 10:39:05 oes
+ * - Added support for escaping the comment character
+ * in config files by a backslash
+ * - Added support for line continuation in config
+ * files
+ * - Fixed a buffer overflow bug with long config lines
+ *
+ * Revision 1.4 2001/05/22 18:56:28 oes
+ * CRLF -> LF
+ *
+ * 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".
+ * - 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 1.2 2001/05/17 23:01:01 oes
+ * - Cleaned CRLF's from the sources and related files
+ *
+ * Revision 1.1.1.1 2001/05/15 13:58:59 oes
+ * Initial import of version 2.9.3 source tree
