Can I get the CSS and Javascript for my application in one HTTP request?

I've been using Rails to develop web sites/apps lately.

I really like their asset pipeline and how it compiles/minifies all of the css and javascript files for production in the css/javascript folders respectively.

I've heard/read in the past that http requests slow down the load time of websites (so naturally, it's best to make as few http requests as possible to reduce the load time of your website).

Is there a way to make rails output css and javascript files from one http request?
