Hi, it took some effort to me to understand this thread, mixing various things.
I would summarize this issue as "XrdHTTP assumes that the path refers to a directory if Depth=1 is specified on a PROPFIND request on a file". Should be not terrible to fix.
I pasted here two examples, showing the issue. (Please do not assume that littlexrdhttp will
work for you in the future, that's my playground)
Example of a working PROPFIND:
$ davix-http -X PROPFIND -P grid https://littlexrdhttp.cern.ch:1094/1M --trace header
HTTP session to https://littlexrdhttp.cern.ch:1094 begins.
PROPFIND /1M HTTP/1.1

Example of a troubled PROPFIND:
$ davix-http -X PROPFIND -H "Depth: 1" -P grid https://littlexrdhttp.cern.ch:1094/1M --trace header
HTTP session to https://littlexrdhttp.cern.ch:1094 begins.
