xrootd-tpc-client does not follow redirects

[VilleS1]

I noticed while testing that xrootd tpc client does not know how to follow redirects. This is in the pool log:

Decoder 3010, channel 2f117595: error for request type redirect : unknown protocol: root: {}. Closing channel.
Exception caught on channel 2f117595: unsupported message type: OutboundEndSessionRequest (expected: ByteBuf, FileRegion)
Uncaught exception in thread xrootd-tpc-client-67

If I put the redirected address directly as source to xrdcp, xrootd tpc copy succeeds.
