case request.user\_agent

‘ie’  
when /(Safari)/  
‘safari’  
else  
‘firefox3’  
end

I can’t test it. But it’s a idea.

Would something like this work for you?

case request.user\_agent  
when /(MSIE 7)/  
‘ie7’  
when /(MSIE 6)/  
‘ie6’  
when /(Firefox 3)/  
‘ff3’  
when /(Firefox 2)/  
‘ff2’  
when /(Firefox 1)/  
‘ff1’  
when /(Safari)/  
‘safari’  
else  
‘unsupported’  
end
