Could you resolve this one already? Still having to build machinery to scrub those out in certain contexts.
I suggest, you look at Zope 4 and check whether the "bobo-*" headers are still there. If so, you may have a chance to convince the maintainers to drop them.
Back in 2003, I said "-1" to a drop because I used
ZPublisher.Clienton behalf of my employer at that time. Meanwhile, I no longer work for her and hold no longer any stake in this question.
Thank you. Went a step further.
