URL hostname rewrite

Got a question from one of my application owners in regards to Remedy (BMC Software). They're looking to have the LTM do the following:   User types in URL http://support.mycompany.com   ...
application delivery

Two options:

  1. You could maintain a data group that maps the name to the IP. Example:

    datagroup (ex. my_server_dg):

10.10.42.10 := server1.domain.com
10.10.42.11 := server2.domain.com
10.10.42.12 := server3.domain.com

iRule:
when HTTP_REQUEST_SEND {
    clientside {
        HTTP::header replace "Host" [class match -value [LB::server addr] equals my_server_dg]
    }
}

  2. If you have internal DNS you could do a quick reverse lookup to get the name.
