Domain is a 'www.xyz.com'. 'www.xyz.com/sub' is not a domain for RealURL. 
Such configuration was never tested and not guaranteed to work.

You also cannot have nested domains (such sub.xyz.com inside www.xyz.com). 
You must have all domains on the top level of the tree, otherwise you may 
have major issues.
