6 * File : $Source: /cvsroot/ijbswa/current/loaders.h,v $
8 * Purpose : Functions to load and unload the various
9 * configuration files. Also contains code to manage
10 * the list of active loaders, and to automatically
11 * unload files that are no longer in use.

40 * Revision 1.11 2001/10/23 21:38:53 jongfoster
41 * Adding error-checking to create_url_spec()
43 * Revision 1.10 2001/09/22 16:36:59 jongfoster
44 * Removing unused parameter fs from read_config_line()
46 * Revision 1.9 2001/07/30 22:08:36 jongfoster
47 * Tidying up #defines:
48 * - All feature #defines are now of the form FEATURE_xxx
49 * - Permanently turned off WIN_GUI_EDIT
50 * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
52 * Revision 1.8 2001/07/29 18:58:15 jongfoster
53 * Removing nested #includes, adding forward declarations for needed
54 * structures, and changing the #define _FILENAME_H to FILENAME_H_INCLUDED.
56 * Revision 1.7 2001/07/13 14:01:54 oes
57 * Removed all #ifdef PCRS
59 * Revision 1.6 2001/06/07 23:14:38 jongfoster
60 * Removing ACL and forward file loaders - these files have
61 * been merged into the config file.
63 * Revision 1.5 2001/05/31 21:28:49 jongfoster
64 * Removed all permissionsfile code - it's now called the actions
65 * file, and (almost) all the code is in actions.c
67 * Revision 1.4 2001/05/29 09:50:24 jongfoster
68 * Unified blocklist/imagelist/permissionslist.
69 * File format is still under discussion, but the internal changes
72 * Also modified interceptor behaviour:
73 * - We now intercept all URLs beginning with one of the following
74 * prefixes (and *only* these prefixes):
76 * * http://ijbswa.sf.net/config/
77 * * http://ijbswa.sourceforge.net/config/
78 * - New interceptors "home page" - go to http://i.j.b/ to see it.
79 * - Internal changes so that intercepted and fast redirect pages
80 * are not replaced with an image.
81 * - Interceptors now have the option to send a binary page direct
82 * to the client. (i.e. ijb-send-banner uses this)
83 * - Implemented show-url-info interceptor. (Which is why I needed
84 * the above interceptors changes - a typical URL is
85 * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
86 * The previous mechanism would not have intercepted that, and
87 * if it had been intercepted then it then it would have replaced
90 * Revision 1.3 2001/05/26 00:28:36 jongfoster
91 * Automatic reloading of config file.
92 * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
93 * Most of the global variables have been moved to a new
94 * struct configuration_spec, accessed through csp->config->globalname
95 * Most of the globals remaining are used by the Win32 GUI.
97 * Revision 1.2 2001/05/20 01:21:20 jongfoster
98 * Version 2.9.4 checkin.
99 * - Merged popupfile and cookiefile, and added control over PCRS
100 * filtering, in new "permissionsfile".
101 * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
102 * file error you now get a message box (in the Win32 GUI) rather
103 * than the program exiting with no explanation.
104 * - Made killpopup use the PCRS MIME-type checking and HTTP-header
106 * - Removed tabs from "config"
107 * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
108 * - Bumped up version number.
110 * Revision 1.1.1.1 2001/05/15 13:59:00 oes
111 * Initial import of version 2.9.3 source tree
