Is there a way I can read the user agent or something similar to determine whether the person is using IE, Mozilla/Netscape, Opera, Safari, etc?

Hi, I am from a Java background and pretty new to Ruby and Rails. What I am wondering is how I would shared state accross requests and users without involving IO, i.e. use memory.
