Here's the header rewrite iRule I got from http://devcentral.f5.com/wiki/iRules.rewrite_host_header_to_server_name.ashx

NOTE: This iRule was tested on a previous version and I current am on 10.2.1 

 
when HTTP_REQUEST_SEND {
      set host_debug 1

      clientside {

            if {$host_debug}{log local0. "[IP::client_addr]:[TCP::client_port]: New [HTTP::method] request to [HTTP::host][HTTP::uri]"}

            set host_header_value [findclass [LB::server addr] ip_to_host_class " "]

            if {$host_debug}{log local0. "[IP::client_addr]:[TCP::client_port]: Looked up [LB::server addr], found: $host_header_value."}

       if {$host_header_value ne ""}{

            HTTP::header replace Host $host_header_value
            if {$host_debug}{log local0. "[IP::client_addr]:[TCP::client_port]: Replaced Host header with $host_header_value."}   
      }
   }
}

nitass I had already added it to the PC host file.
