Hi,

try this:

You just need to modify IP by your backend IP and needed host.

when LB_SELECTED {

if { [LB::server addr] eq "10.1.1.1" } {
    set host "1.site.com"       
} elseif { [LB::server addr] eq "10.1.1.2" } {
    set host "2.site.com"
} elseif { [LB::server addr] eq "10.1.1.3" } {
    set host "3.site.com"
} else {
    set host [HTTP::header "Host"]
}


}

HTTP_REQUEST_RELEASE {
if { [HTTP::header exists "Host"] } {
    HTTP::header replace Host $host
  } else {
    HTTP::header insert Host $host
  }
}
}

Keep me in touch. regards,
