redis usage is broken #27
Description
The mistake was introduced here: acbe674#diff-3e3173a50db7d7cd7e3561efce0f0e8aR68
The problem is that for e.g. http://127.0.0.1:8765/1 InetPath produces path segments ["", "1"], so getting the first one and converting to long doesn't work.
I don't know whether this is a bug in InetPath or in userman, but it completely breaks userman w/ redis.
