1.4.14 had a regression with response cookie processing, causing crashes if some response cookie had a space in them. From what I recall, it could only be triggered by "capture cookie" or cookie prefix mode. But this version did not last long as 1.4.15 was emitted with just this fix a few days later. I'd call this "bad luck" :-) Willy
