RPC path truncated when it starts with "/transmission/rpc"

[runapp]

I'm running v5.18.0 on Windows, and found that when rpc path is set to /transmission/rpc/test, I got a request of POST /transmission/rpc HTTP/1.1 on server (acually nginx). However, if I change the rpc path to /transmission/rp/test, the server would receive a correct request.

I've no idea on that, cause the magic string /transmission/rpc only exists in rpc.pas and I can't find anything wrong with FRpcPath.
