Multiple domains and subdomains may be aliases of the same canonical domain. For example, www.example.com may be an alias of example.com.
In these cases, we do not want to define separate configurations for all aliases. Instead, we want to define configuration files for the canonical domain, and use wiki redirect statements to point aliases to these configurations.
Make sure Web2Cit follows these redirect statements, which is currently not the case as reported by @Kerry_Raymond.
