        if (fwdState->servers->next) {
            /* use next, or cycle if origin server isn't last */

  so

   Peer1 -> Peer2 -> Peer3 -> Origin

  becomes

   Peer1 -> Peer2 -> Peer3 -> Origin -> Origin -> Origin -> Origin ->
Origin -> Origin -> ...

  but

   Peer1 -> Peer2 -> Origin -> Peer3

  becomes

   Peer1 -> Peer2 -> Origin -> Peer3 -> Peer1 -> Peer2 -> Origin ->
Origin -> Origin -> Origin

until a viable path is found.

If there is a timeout then fwdConnectTimeout is called, which closes the
unconnected server connection, which triggers fwdServerClosed().

If there is an error then the server connecion is closed, which triggers
fwdServerClosed().

If there is a response then the server connection is closed when the
response have been received, which triggers fwdServerClosed().

In all cases fwdServerClosed() verifies if the request has to be
retried, and then selects the next possible path if it has to.
