* $Log: loadcfg.c,v $
+ * Revision 1.88 2009/02/28 10:57:10 fabiankeil
+ * Gimme a break or two. Don't let the show-status page
+ * link to the website documentation for the user-manual
+ * directive itself.
+ *
+ * Revision 1.87 2009/02/15 07:56:13 fabiankeil
+ * Increase default socket timeout to 300 seconds.
+ *
+ * Revision 1.86 2009/02/08 19:18:57 fabiankeil
+ * Now that we have the match-all.action file, the other action
+ * files changed their position in config->actions_file[] back
+ * to the way it was before standard.action got removed and the
+ * changes from revision 1.84 have to be reverted.
+ *
+ * Revision 1.85 2009/01/22 12:06:26 fabiankeil
+ * Don't keep connections alive when running single-threaded.
+ *
+ * Revision 1.84 2009/01/14 16:14:36 fabiankeil
+ * Due to the standard.action file removal, the other action
+ * files changed their position in config->actions_file[].
+ * Update mingw32 kludge accordingly.
+ *
+ * Revision 1.83 2008/12/20 14:53:55 fabiankeil
+ * Add config option socket-timeout to control the time
+ * Privoxy waits for data to arrive on a socket. Useful
+ * in case of stale ssh tunnels or when fuzz-testing.
+ *
+ * Revision 1.82 2008/11/16 12:43:49 fabiankeil
+ * Turn keep-alive support into a runtime feature
+ * that is disabled by setting keep-alive-timeout
+ * to a negative value.
+ *
+ * Revision 1.81 2008/11/13 09:08:42 fabiankeil
+ * Add new config option: keep-alive-timeout.
+ *
+ * Revision 1.80 2008/08/31 15:59:03 fabiankeil
+ * There's no reason to let remote toggling support depend
+ * on FEATURE_CGI_EDIT_ACTIONS, so make sure it doesn't.
+ *
* Revision 1.79 2008/08/30 12:03:07 fabiankeil
* Remove FEATURE_COOKIE_JAR.
