Hi @bbockelm , Thanks for the tips :) I managed to have the trailer working indeed. If I add your snippet of code, I indeed get the trailer: ``` X-Transfer-Status: 500: Unable to read /tmp/bigfile_5M_copy; input/output error ``` Is it normal that I get a 200 OK response though ? ``` > GET /tmp/bigfile_5M_copy HTTP/1.1 > User-Agent: curl/7.29.0 > Host: xrootd-ccaffy-dev01.cern.ch:1096 > Accept: */* > X-Transfer-Status: true > TE: trailers > Transfer-Encoding: chunked > < HTTP/1.1 200 OK < Connection: Keep-Alive < Server: XrootD/v5.2.0-99-osghotfix...687 < Content-Length: 5000000 < Transfer-Encoding: chunked < { [data not shown] 20 4882k 20 1024k 0 0 6266k 0 --:--:-- --:--:-- --:--:-- 6282k [FILE CONTENT] X-Transfer-Status: 500: Unable to read /tmp/bigfile_5M_copy; input/output error * Connection #0 to host xrootd-ccaffy-dev01.cern.ch left intact ``` -- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/pull/1912#issuecomment-1439724767 You are receiving this because you are subscribed to this thread.
