Subject: h2h3: fix overriding the 'TE: Trailers' header
X-Git-Tag: curl-7_85_0~157
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=b9b6148c45a00d675d5bb261bf4cbb45468ad807;p=thirdparty%2Fcurl.git

h2h3: fix overriding the 'TE: Trailers' header

A 'TE: Trailers' header is explicitly replaced by 'te: trailers'
(lowercase) in Curl_pseudo_headers() when building the list of HTTP/2 or
HTTP/3 headers. However, this is then replaced again by the original
value due to a bug, resulting in the uppercased version being sent. Some
HTTP/2 servers reject the whole HTTP/2 stream when this is the case.

Closes #9170
