irule to check if iPad is used when making connection

Hello,

 

We have following checks done:

 

when HTTP_REQUEST { check for browser-type switch -glob [HTTP::header value "User-Agent"] { "MSIE 6" - "MSIE 7" - "MSIE 8" { do stuff }

 

Now we should have to add another check to verify if an iPAD is used (and do some actions accordingly) ? Any idea how this can be checked ?

 

Thanks in advance, Frederik
