Redirect based on user browser (mobile)

I am writing an iRule that states if the user is coming in via a mobile device to get redirected to a different pool. My question, here is what I have, is this correct?     when HTTP_REQUEST { ...

I assume the request you expect to be redirected but isn't being redirected is being made with a host header which matches *mobile*, but isn't a mobile user-agent. Here are a few modifications to your version. You could use the logging in this example to troubleshoot your version. 

 
  
 when HTTP_REQUEST { 
  
    log local0. "[IP::client_addr]:[TCP::client_port]: New request from [HTTP::header User-Agent]\ 
       to [HTTP::host][HTTP::uri]" 
  
    if {([string tolower [HTTP::host]] contains "mobile")} {  
       switch -glob [string tolower [HTTP::header User-Agent]] { 
          "*blackberry*" -  
          "*java/1.4.1_02*" -  
          "*blazer*" -  
          "*palm*" -  
          "*smartphone*" -  
          "*danger*" -  
          "*hiptop*" -  
          "*mot-*" -  
          "*razr*" -  
          "*audiovox*" -  
          "*symbian*" -  
          "*nokia*" -  
          "*sony ericsson*" -  
          "*samsung*" -  
          "*lb 8*" -  
          "*alcatel 735i*" -  
          "*nextel*" -  
          "*windows ce*" -  
          "*netfront*" {   
             pool mobile_pool 
             log local0. "[IP::client_addr]:[TCP::client_port]: Matched Host and User-Agent checks" 
          } 
          default { 
              Request didn't match User-Agent check 
             HTTP::redirect "http://non_mobile_website.com" 
             log local0. "[IP::client_addr]:[TCP::client_port]: Request didn't match User-Agent check" 
          } 
       } 
    } else {  
        Request didn't match Host header check 
       HTTP::redirect "http://non_mobile_website.com" 
       log local0. "[IP::client_addr]:[TCP::client_port]: Request didn't match Host check" 
    }  
 }
