I like it. You also need to document it in the README.

I would change redirect to take an optional code and default it to nil, which causes it to be a 302/303. People might want permanent redirects and stuff like that (304).

@dblock thanks. let me change it

I am going to nitpick, but since we're at it, do you think it's worth changing permanent = true to an options hash? So that I can do redirect url, permanent: true. It's more explicit and extensible, although I am struggling to find what we'll extend it to?

Leaving this open for a couple of days before merging! Speak up if you have an opinion.

@dblock I've considered it before, I think user will do permanent redirect in web server in most of the case, so I use false as default value.

[dblock]

I meant like this:

def redirect(url, options = {})
   # permanent redirect if options[:permanent]
end

That is if we think there will be more to options than permanent vs. non-permanent?
