You can define the two different groups of destination hosts in two separate pools:

special_pool

1.1.1.1:80

1.1.1.2:80

1.1.1.3:80

1.1.1.4:80

main_pool

1.1.1.1:8080

1.1.1.2:8080

1.1.1.3:8080

1.1.1.4:8080

And then define the set of client IP addresses you want sent to special_pool in a datagroup of type 'address'. You can create a datagroup under Local Traffic >> iRules >> Datagroups.

You can then use an iRule which checks the client IP address against a datagroup:

 
 when CLIENT_ACCEPTED { 
  
     Check if client is in special_clients datagroup 
    if {[matchclass [IP::client_addr] equals $::special_clients]}{ 
  
        Use the special pool 
       pool special_pool 
    } else { 
       pool main_pool 
    } 
 }
