* $Log: loadcfg.c,v $
+ * Revision 1.79 2008/08/30 12:03:07 fabiankeil
+ * Remove FEATURE_COOKIE_JAR.
+ *
+ * Revision 1.78 2008/08/02 08:23:22 fabiankeil
+ * If the enforce-blocks directive is used with FEATURE_FORCE_LOAD
+ * disabled, log a message that blocks will always be enforced
+ * instead of complaining about an unrecognized directive.
+ * Reported by Pietro Leone.
+ *
+ * Revision 1.77 2008/05/26 16:13:22 fabiankeil
+ * Reuse directive_hash and don't hash the same directive twice.
+ *
+ * Revision 1.76 2008/05/10 09:03:16 fabiankeil
+ * - Merge three string_append() calls.
+ * - Remove useless assertion.
+ *
+ * Revision 1.75 2008/03/30 14:52:05 fabiankeil
+ * Rename load_actions_file() and load_re_filterfile()
+ * as they load multiple files "now".
+ *
+ * Revision 1.74 2008/03/26 18:07:07 fabiankeil
+ * Add hostname directive. Closes PR#1918189.
+ *
+ * Revision 1.73 2008/02/16 16:54:51 fabiankeil
+ * Fix typo.
+ *
+ * Revision 1.72 2008/02/03 13:46:15 fabiankeil
+ * Add SOCKS5 support. Patch #1862863 by Eric M. Hopper with minor changes.
+ *
+ * Revision 1.71 2007/12/23 15:24:56 fabiankeil
+ * Reword "unrecognized directive" warning, use better
+ * mark up and add a <br>. Fixes parts of #1856559.
+ *
+ * Revision 1.70 2007/12/15 14:24:05 fabiankeil
+ * Plug memory leak if listen-address only specifies the port.
+ *
+ * Revision 1.69 2007/10/27 13:02:27 fabiankeil
+ * Relocate daemon-mode-related log messages to make sure
+ * they aren't shown again in case of configuration reloads.
+ *
+ * Revision 1.68 2007/10/19 16:32:34 fabiankeil
+ * Plug memory leak introduced with my last commit.
+ *
+ * Revision 1.67 2007/10/14 14:12:41 fabiankeil
+ * When in daemon mode, close stderr after the configuration file has been
+ * parsed the first time. If logfile isn't set, stop logging. Fixes BR#897436.
+ *
+ * Revision 1.66 2007/08/05 14:02:09 fabiankeil
+ * #1763173 from Stefan Huehner: declare unload_configfile() static.
+ *
+ * Revision 1.65 2007/07/21 11:51:36 fabiankeil
+ * As Hal noticed, checking dispatch_cgi() as the last cruncher
+ * looks like a bug if CGI requests are blocked unintentionally,
+ * so don't do it unless the user enabled the new config option
+ * "allow-cgi-request-crunching".
+ *
+ * Revision 1.64 2007/05/21 10:44:08 fabiankeil
+ * - Use strlcpy() instead of strcpy().
+ * - Stop treating actions files special. Expect a complete file name
+ * (with or without path) like it's done for the rest of the files.
+ * Closes FR#588084.
+ * - Remove an unnecessary temporary memory allocation.
+ * - Don't log anything to the console when running as
+ * daemon and no errors occurred.
+ *
+ * Revision 1.63 2007/04/09 18:11:36 fabiankeil
+ * Don't mistake VC++'s _snprintf() for a snprintf() replacement.
+ *
+ * Revision 1.62 2007/03/17 15:20:05 fabiankeil
+ * New config option: enforce-blocks.
+ *
+ * Revision 1.61 2007/03/16 16:47:35 fabiankeil
+ * - Mention other reasons why acl directive loading might have failed.
+ * - Don't log the acl source if the acl destination is to blame.
+ *
+ * Revision 1.60 2007/01/27 13:09:16 fabiankeil
+ * Add new config option "templdir" to
+ * change the templates directory.
+ *
* Revision 1.59 2006/12/31 17:56:38 fabiankeil
* Added config option accept-intercepted-requests
* and disabled it by default.
