Glad you liked it . The idea was to show how simple is to create a piece of middleware. I follow the same approach you are, and I honestly wouldn’t use this in production.

Anyways, you can check out http://github.com/rtomayko/rack-contrib/ where there are more interesting and useful pieces of middleware

Thanks for the idea. I have been writing a web application using the ExtJS framework and what I do before deploying the application to production is combine all of my individual class files into a single file, then minify them, and in the production environment I just refer to the compressed file…

Are there any advantages to running the minification step at the request level?

In either case , you’ve given me a bunch of ideas to try out Rack. thanks
