HTTP PUT is meant to be an idempotent operation: https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/PUT That is, it should be possible to PUT multiple times against the same resource - i.e., it should allow overwrites. Unfortunately, XRootD does not do this - it disallows overwrites. Seems to be as simple as changing this line: https://github.com/xrootd/xrootd/blob/master/src/XrdHttp/XrdHttpReq.cc#L1093 -- You are receiving this because you are subscribed to this thread.
