Ruby as a scripting language for a web server

Question

Can Ruby be used as a scripting language with an HTTP server? I would like to be able to simply put some Ruby files in a web directory and be able to execute them from my browser - just like I did with PHP.

I have absolutely nothing against frameworks like RoR, but they told me that I should first learn Ruby and only then move on to higher levels. Of course, I could write some Ruby scripts and run them in the console, but I would rather get in / out from my browser :)

Is this even possible? Otherwise, how difficult would it be to build a fast and simple web infrastructure?
