Since the 2.6, A parsing error is reported when the chunked encoding is found twice. As stated in RFC9112, A sender must not apply the chunked transfer coding more than once to a message body. It means only one chunked coding must be found. In addition, empty values are also rejected becaues it is forbidden by RFC9110. However, in both cases, it may be useful to relax the rules for trusted legacy servers when accept-invalid-http-response option is set. Especially because it was accepted on 2.4 and older. In addition, T-E header is now sanitized before sending it. It is not a problem Because it is a hop-by-hop header Note that it remains invalid on client side because there is no good reason to relax the parsing on this side. We can argue a server is trusted so we can decide to support some legacy behavior. It is not true on client side and it is highly suspicious if a client is sending an invalid T-E header. Note also we continue to reject unsupported T-E values (so all codings except "chunked"). Because the "TE" header is sanitized and cannot contain other value than "Trailers", there is absolutely no reason for a server to use something else. This patch should fix the issue #2677. It could probably be backported as far as 2.6 if necessary.
