Selectivly send requests to encrypted or non-encrypted pools

You could explicitly add a default case to the iRule or add a OneConnect profile to the virtual server to prevent this.

  
 when CLIENT_ACCEPTED {  
     Save default pool name  
    set default_pool [LB::server pool]  
 }  
 when HTTP_REQUEST {  
    if { ([HTTP::path] starts_with "/irj") } { 
       pool test-pool 
    } else { 
       pool $default_pool 
    } 
 }  
 when SERVER_CONNECTED { 
    if {[LB::server pool] eq "test-pool"} { 
       SSL::disable 
    } 
 }
