You could create a separate pool for each host header value and then use HTTP classes to select the corresponding pool. Or if you wanted to use an iRule you could use something like this: 


when HTTP_REQUEST {

    Check the requested host header set to lower case with wildcard matching
   switch -glob [string tolower [HTTP::host]] {
      "a.example.com" {
         pool pool_a
      }
      "b.example.com" {
         pool pool_b
      }
      "c.example.com" {
         pool pool_c
      }
      default {
         pool default_pool
      }
   }
}
