# By rescuing the exceptions, execution will continue and the rest of the URLs will be
# downloaded.
# We can notice that we could have one the following: Down::TooLarge, Down::InvalidUrl,
# Down::TooManyRedirects, Down::ResponseError, Down::ClientError, Down::NotFound,
# Down::ServerError, Down::ConnectionError, Down::TimeoutError, Down::SSLError.
