Using iRules to conserve public IP addresses

Hello all,

I've been tasked with coming up with a solution using one public IP address and laod balancing it to multiple pools using iRules and host-headers. Currently, we're doing a one to one NAT. I created a virtual server and used the iRule below, which is using Data Groups. I was able to successfully accomplish this for http but I cannot get https to work. If anyone can provide some input, I'd much appreciate it.

    when HTTP_REQUEST {
if { [class match [string tolower [HTTP::host]] equals TestRedirect] } {
  set usepool [class match -value [string tolower [HTTP::host]] equals TestRedirect]
  pool $usepool
}
}

Here is the Data Group for the http pools.

ltm data-group internal /Common/TestRedirect { 
    records { 
        TESTA.net { 
            data TESTA_80_pool 
        } 
        TESTB.org { 
            data TESTB_80_pool 
        } 
        TESTC.com { 
            data TESTC_80_pool 
        } 
    } 
    type string 
}
