Redirect if your a mobile user....

when HTTP_REQUEST { 
 if { [HTTP::header "User-Agent" ] contains $::MobileUserAgents } { 
 HTTP::redirect "http://mobile.holidayextras.co.uk[HTTP::uri]"  
 log local0. "iPhone Found" 
 } 
  
 Uncomment the line below to turn on logging. 
 log local0.  "Mobile Redirected: [HTTP::header "User-Agent"] -Phone Redirected" 
 }code] 
  
 My DataGroup is a string with.... 
 *iPhone* 
 *iPad* 
 *iPod* 
 I like My Apple stuff! 
  
 But the iRule dosn't seem to be working as nothing is being written to the log, if I turn on the global log I can see iPhone user agents passing through....

 I'm confused! 
  
 Also you said if I'm running 9.4.4 then I should remove the $:: from the datagroup, I have 9.4.8 HF4 running but it wont let me take out the $::, when I try and pass the rule through the irule editor it keeps telling me my irule is invalid. 
  
 Thank you for your help guys!
