Answer 1

Try:

request.user_agent

Answer 2

Are you using Apache or nginx in front of your mongrel(s)?

Are you logging the user_agent? This is from my nginx.conf:

log_format main '$remote_addr - $remote_user [$time_local] $request '
                  '"$status" $body_bytes_sent "$http_referer" '
                  '"$http_user_agent" "http_x_forwarded_for"';
