How about this:
sub vcl_recv {
unset req.http.hash_input; // Don't confuse me
if (req.url == "/" &&
req.http.User-Agent ~ "^Mozilla/5.0 \(iP(hone|od);" &&
!req.http.User-Agent ~ "somecookie" ) {
set req.backend = someother;
set req.http.hash_input = "iphone";
}
}
sub vcl_hash {
set req.hash += req.http.hash_input;
}
