Subject: [PATCH] http: unset `F_CHUNKED` on new `Transfer-Encoding`
|
||||
|
||||
Duplicate `Transfer-Encoding` header should be a treated as a single,
|
||||
but with original header values concatenated with a comma separator. In
|
||||
the light of this, even if the past `Transfer-Encoding` ended with
|
||||
`chunked`, we should be not let the `F_CHUNKED` to leak into the next
|
||||
header, because mere presence of another header indicates that `chunked`
|
||||
is not the last transfer-encoding token.
