The redirection could be done within a frame. If mirror answers the page
in less than x seconds, the page will load and a frame-breaker will
destroy it. If not, the second frame can switch to the next server.
Worst case for the server: it is busy answering petitions which, by the
time it has the answer, the client is asking to another server. :/
