Data Group List use in a switch

I do something like this to do a two factor firewall type rule that includes a src ip whitelist chained to particular URI prefix's. I really like this and its not terrible to read/maintain and uses switch plus datagroups for the win

when HTTP_REQUEST {
   switch -glob [URI::decode [string tolower [HTTP::uri]]] {
      /customer1* { if { ([class match [IP::remote_addr] equals $::customer1_ip_whitelist]) } { return } }   
      /customer2* { if { ([class match [IP::remote_addr] equals $::customer2_ip_whitelist]) } { return } }   
      /customer3* { if { ([class match [IP::remote_addr] equals $::customer3_ip_whitelist]) } { return } }   
      default {
         discard
      }
   }
   HTTP::redirect "http://srypage.acme.com/sorry/nac/?hn=[HTTP::host][HTTP::uri]"
}
I suppose to just check the URI against the datagroup instead of the src ip, it could be changed inline for each condition
Hope this helps
Thanks
