* Revisions :
* $Log: loaders.c,v $
+ * Revision 1.68 2008/09/19 15:26:28 fabiankeil
+ * Add change-x-forwarded-for{} action to block or add
+ * X-Forwarded-For headers. Mostly based on code removed
+ * before 3.0.7.
+ *
+ * Revision 1.67 2008/03/30 14:52:08 fabiankeil
+ * Rename load_actions_file() and load_re_filterfile()
+ * as they load multiple files "now".
+ *
+ * Revision 1.66 2008/03/21 11:16:30 fabiankeil
+ * Garbage-collect csp->my_ip_addr_str and csp->my_hostname.
+ *
+ * Revision 1.65 2007/12/07 18:29:23 fabiankeil
+ * Remove now-obsolete csp member x_forwarded.
+ *
+ * Revision 1.64 2007/06/01 14:12:38 fabiankeil
+ * Add unload_forward_spec() in preparation for forward-override{}.
+ *
+ * Revision 1.63 2007/05/14 10:41:15 fabiankeil
+ * Ditch the csp member cookie_list[] which isn't used anymore.
+ *
+ * Revision 1.62 2007/04/30 15:02:18 fabiankeil
+ * Introduce dynamic pcrs jobs that can resolve variables.
+ *
+ * Revision 1.61 2007/04/15 16:39:21 fabiankeil
+ * Introduce tags as alternative way to specify which
+ * actions apply to a request. At the moment tags can be
+ * created based on client and server headers.
+ *
+ * Revision 1.60 2007/03/20 15:16:34 fabiankeil
+ * Use dedicated header filter actions instead of abusing "filter".
+ * Replace "filter-client-headers" and "filter-client-headers"
+ * with "server-header-filter" and "client-header-filter".
+ *
+ * Revision 1.59 2007/01/25 13:38:20 fabiankeil
+ * Freez csp->error_message in sweep().
+ *
+ * Revision 1.58 2006/12/31 14:25:20 fabiankeil
+ * Fix gcc43 compiler warnings.
+ *
* Revision 1.57 2006/12/21 12:22:22 fabiankeil
* html_encode filter descriptions.
