Hello, We are considering using an xrootd system to manage file transfers to our site which we would like to support transfers using both the https and (x)root protocols. I have a test system set up and am able to do normal file transfers over both protocols as well as third party copy (tpc) over (x)root but I am struggling to have a successful tpc over https. I am using the gfal2 client to manage the transfers and require that the tpc go directly between the servers and not through the client initiating the copy, so a typical request would look like "gfal-copy -- copy-mode pull https://testserver1:8443//storage/file.txt https://testserver2:8443//storage/ " I have attached my xrootd config file as well. The error I get when I try to do this seems to be a "unable to locate /storage/file.txt: no such file or directory" on the destination server but this does not make sense since the file shouldn't be there as it is going to be copied over. I also noticed the libXrdHttpTPC-5.so file but after invoking it with http.exthandler nothing seemed to change. I am probably just missing a configuration value or not issuing my command correctly but any help is appreciated.
