not sure if i understand correctly or not. this is an example. i used http instead of https because it is a bit easier to display http header. 

[root@ve1023:Active] config  b virtual bar list
virtual bar {
   snat automap
   pool foo
   destination 172.28.19.79:80
   ip protocol 6
   rules myrule
   profiles {
      http {}
      tcp {}
   }
}
[root@ve1023:Active] config  b pool foo list
pool foo {
   members {
      200.200.200.101:80 {}
      200.200.200.102:80 {}
   }
}
[root@ve1023:Active] config  b rule myrule list
rule myrule {
   when HTTP_REQUEST {
        if {[string tolower [HTTP::host]] equals "aaa.com"}{
                if {[string tolower [HTTP::uri]] starts_with "/testing"}{
                        HTTP::uri "/go[HTTP::uri]"
                }
        }
}

when HTTP_REQUEST_SEND {
        clientside {
                HTTP::header replace Host [class match -value [LB::server addr] equals ip_to_host]
        }
}
}
[root@ve1023:Active] config  b class ip_to_host list
class ip_to_host {
   {
      "200.200.200.101" { "bbb.com" }
      "200.200.200.102" { "ccc.com" }
