Abstract
A redirection device and method, relating to identification of a data server capable of delivering content to a terminal, initiated by the transfer to a second name server of a second domain of a message for obtaining an identifier of the data server in the second domain received from the terminal. Following this transfer, the second name server sends a redirection message to a first domain, including a delegation chain including first data for redirection from the second domain to the first domain. The chain is updated recursively with the redirections between domains added by respective name servers until a name server is able to provide an identifier of the data server.
