Simple web site - Rails, Nitro, Others?

[Dan]

Hi,

I've developed a mid-sized web application in rails, but I'm not sure
rails is the right choice for my latest project.

I need to put together a web site with a handful of pages and a few
dynamic elements driven by interactive web service lookups. I don't
need a database and don't expect the site to expand a lot, but would
like to have some integrated page level caching.

I'd prefer to use ruby, but I only need the simplest of web frameworks
(even something PHPish would probably do). I found Nitro, but the
lack of documentation scares me - I don't want to spend weeks trying
to figure out how to do simple things Any suggestions? Also, is
anyone using nitro in a production app?

Thanks!
Dan
