Now on Heroku

I now changed my hosting to Heroku. I believe it will be far more reliable.

But as you should know my website is completely static. I use nanoc to generate it. But here is the conf to make it work on heroku.

The root of my files is /output. You only need to create a config.ru¹ file:

require 'rubygems' require 'rack' require 'rack/contrib' require 'rack-rewrite' require 'mime/types'

use Rack::ETag module ::Rack class TryStatic < Static

    def initialize(app, options)
        super
        @try = ([''] + Array(options.delete(:try)) + [''])
    end

    def call(env)
        @next = 0
        while @next < @try.size && 404 == (resp = super(try_next(env)))[0] 
            @next += 1
        end
        404 == resp[0] ? @app.call : resp
    end

    private
    def try_next(env)
        env.merge('PATH_INFO' => env['PATH_INFO'] + @try[@next])
    end

end

end

use Rack::TryStatic, :root => "output", # static files root dir :urls => %w[/], # match all requests :try => ['.html', 'index.html', '/index.html'] # try these postfixes sequentially

errorFile='output/Scratch/en/error/404-not_found/index.html' run lambda { [404, { "Last-Modified" => File.mtime(errorFile).httpdate, "Content-Type" => "text/html", "Content-Length" => File.size(errorFile).to_s }, File.read(errorFile)] }

and the .gems file needed to install rack middlewares.

rack rack-rewrite rack-contrib

Now, just follow the heroku tutorial to create an application :

git init git add . heroku create git push heroku master

Now I'll should be able to redirect properly to my own 404 page for example. I hope it is helpful.
