save url parameter in a session

Hi, I am a newb.

Lets say I have url abc.com/?animal=cat. What I need to do is save the param in the session file but still have it available to other controllers. I can get it to work within one controller with:

session[:animal] = param[:animal]

but I cannot get it to save and be used by other controllers. I can hack it by adding:

session[:animal] = "cat"

in the application.rb and adding a before filter to the controller. How do I add a param from a url in a session to be used by all controllers?

Thanks!

There's no reason that shouldn't work. If there's something you're
doing wrong you haven't shown us that bit yet.

So sessions are not cleared out controller to controller? I found another way (prob. a better way), I am using the redirect_to to pass the variable. The funny thing about problems is that you need to know what the question is before you can solve it I guess... Thanks!

Nope. would rather defeat the point of the session

That sounds like a sane way to do it.
