OK I understand better now. However, I think that this transformation is very specific and if we go down that route we'll have many similar ones. I suggest that instead we focus on applying sed-like regex-based transformations which will allow this and many other things at the same time. Also, in your case, you seem to apply the change to the first header found only, though in theory it should be applied to every header value or every header line depending on the use case. That's probably one more reason for doing it a-la-sed :-) Best regards, Willy
