Hi Puli,

 

You can pull this from the HTTP header fields.

 

 

Specifically HTTP header field called Accept-language header

 

Click Here to go to a link that discusses accept-language header

 

 

As for the code I suppose you can use a untested iRule scripts like the following

 

 


when HTTP_REQUEST {

      if { [HTTP::header "Accepted-Language"] contains "fr" }  {

           HTTP::redirect http://www.abc.com/fr/help
     
         }

}

 

 

or you can go switch command route if you have many different language pages.

 

 


when HTTP_REQUEST {
   
      switch -glob [HTTP::header "Accepted-Language"] {
      
     "*fr*" - { HTTP::redirect http://www.abc.com/fr/help }
      
     "*en-us*" - { HTTP::redirect http://www.abc.com/fr/help }

      default - { HTTP::redirect http://www.abc.com/help }
   
      }

}

 

 

The tool that I normally use is the HTTPFox to quickly look at the language my browser is set to. Click Here to see view how you can switch languages on the browser level.

 

 

I hope this helps
