host header load-balancing

So you just need to rewrite the URI?

when HTTP_REQUEST {
    switch -glob [HTTP::header value "User-Agent"] {
        "*MSIE 6*" -
        "*MSIE 7*" -
        "*MSIE 8*" {
            pool site-10.130.14.98_9610
            HTTP::uri "/login"
        }
        default {
            pool site-10.130.14.98_29710
        }
    }
}
