    If you VIP hosts single domain then use this to whitelist it

    when HTTP_REQUEST {
     switch [string tolower [HTTP::host]] {
     "www.domain.com" 
      {
       return
      }
     default { 
       reject
      }
     }
    }

    If VIP hosts multiple domains/SAN use below to whitelist all

    when HTTP_REQUEST {
     switch [string tolower [HTTP::host]] {
     "www.domain1.com" -
     "www.domain2.com" -
     "www.domain3.com" 
     {
       return
      }
     default { 
       reject
      }
     }
    }
