similar to: ActiveRecord attribute= overload

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?

Thanks, - Brent

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. My current understanding is that for each request a new process ist spawn and therefore it gets its own memory. So no sharing can take place between requests? Do I understand this right? For those who know

I know that Rails 1.1-RC1 has many new features but it also seems to fix numerous bugs found in Rails 1.1.

I heard 1.1-RC1 gets rid of the ''white screen of death'' but I''m wondering if any new bugs
