Description Julian Reschke 2012-01-10 13:56:43 UTC
The list of "author request headers" mentions Content-Transfer-Encoding. This is confusing as there is no such header field in HTTP (there is one in email, though).
Comment 1 Anne 2012-01-10 14:01:32 UTC
I think you are confusing author request headers with headers that cannot be set by authors. What is wrong with prohibiting Content-Transfer-Encoding?

a) yes, sorry.

b) as I said: what's the point in forbidding it when it doesn't exist?
Comment 3 Anne 2012-01-10 14:32:43 UTC
I don't know.
Comment 4 Boris Zbarsky 2012-01-10 17:05:36 UTC
Julian is right: there is no such header, so prohibiting it makes no sense.  Why was that text added to the spec?  Did it actually mean to prohibit setting Content-Encoding or Transfer-Encoding (or maybe both?)
Comment 5 Anne 2012-01-10 17:09:20 UTC
Not sure. The header has been there since the draft of June 2007.

Transfer-Encoding is forbidden. I think the idea must have been to forbid Content-Encoding.
Comment 8 Anne 2012-05-14 14:18:44 UTC
I removed Content-Transfer-Encoding.
