You use two */virtual files. how do we know which one you describe here?

note that it is also possible that the configuration you post here is
different from your actual configuration. nothing proves that your
obfuscation preserves the configuration. you may want to add a real user
(user1) to minimize the need for obfuscation (so that only the domain is
replaced by example.org).
