Browser caching of js and css

I'm running https connection to apache 2.2 proxying to mongrel running rails 1.2. The browser never caches my js and css files. Is there some way to tell it to cache them.

We talking in development or production? Development Rails adds a random number string to the script and link tags to make sure there is no caching. If this is production, make sure your browser cache isn’t actually turned off.
