Hi Sean,

The rule looks fine as far as the syntax goes. Can you add logging to the iRule and provide more detail on which requests fail and what log output you see for a failure? 

 
 when HTTP_REQUEST { 
  
    log local0. "[IP::client_addr]:[TCP::client_port]: New request to [HTTP::host][HTTP::uri]" 
    if { [matchclass [HTTP::uri] contains $::siloSIRSI ] } { 
       log local0. "[IP::client_addr]:[TCP::client_port]: Using pool syndetics2.com-linux" 
       pool syndetics2.com-linux 
    } elseif { [matchclass [HTTP::uri] contains $::clientURI ] } { 
       log local0. "[IP::client_addr]:[TCP::client_port]: Using pool syndetics.com-linux" 
       pool syndetics.com-linux 
    } elseif { [matchclass [HTTP::uri] contains $::badclient ] } { 
       log local0. "[IP::client_addr]:[TCP::client_port]: Using pool Bad_Clients" 
       pool Bad_Clients 
    } else { 
       log local0. "[IP::client_addr]:[TCP::client_port]: Using pool Syndetics.com" 
       pool Syndetics.com 
    } 
 }
