* $Log: parsers.c,v $
+ * Revision 1.103 2007/06/01 16:31:54 fabiankeil
+ * Change sed() to return a jb_err in preparation for forward-override{}.
+ *
+ * Revision 1.102 2007/05/27 12:39:32 fabiankeil
+ * Adjust "X-Filter: No" to disable dedicated header filters.
+ *
+ * Revision 1.101 2007/05/14 10:16:41 fabiankeil
+ * Streamline client_cookie_adder().
+ *
+ * Revision 1.100 2007/04/30 15:53:11 fabiankeil
+ * Make sure filters with dynamic jobs actually use them.
+ *
+ * Revision 1.99 2007/04/30 15:06:26 fabiankeil
+ * - Introduce dynamic pcrs jobs that can resolve variables.
+ * - Remove unnecessary update_action_bits_for_all_tags() call.
+ *
* Revision 1.98 2007/04/17 18:32:10 fabiankeil
* - Make tagging based on tags set by earlier taggers
* of the same kind possible.
* headers (client or server)
* 3 : csp = Current client state (buffers, headers, etc...)
*
- * Returns : Single pointer to a fully formed header, or NULL
- * on out-of-memory error.
+ * Returns : JB_ERR_OK in case off success, or
+ * JB_ERR_MEMORY on out-of-memory error.
