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 {

 

if {[HTTP::header User-Agent] contains "Mozilla"}

 

{pool default-pool} else {pool mobile-pool}

 

 

I was givin a list of known mobile user agents to look for but wouldn't it be easier to just look for the non mobile user agents?

 

 

Version 9.4 HF4

    Indeed, "return 0" gets rid of the error 😄

    
when HTTP_REQUEST {
 if {([string tolower [HTTP::host]] contains "my.com")} {
  switch -glob [HTTP::header User-Agent] {
   "*BlackBerry*" -
   "*Blackberry*" -
   "*Java/1.4.1_02*" -
   "*Blazer*" -
   "*blazer*" -

    return 0
   }
  } 
  switch -glob [HTTP::header Accept] {
   "*text/vnd.wap.wml*" { 
    pool mobile_pool
   }
  }
 }
}

    edit: Used the wrong rule, is correct now

    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" 
    }  
 }
