Rails - Apr 2010 - /lib/rack/request.rb in my gem - is this reserved?

Hi!

I write a gem at the moment. The Gem need to register during the
process in the rack middleware.
So I make an folder "rack" inside my "lib" folder. I called
the file
"request.rb" because it keeps track of requests.

So we speaking about the file /lib/rack/request.rb

But even if I place an empty file on this, I get the following:

It seems like something does require a module Rack; class Request;
inside of this file.
What is the cause of this? Where can I find ressources concerning this
issue?

This works perfectly find, if I put this file under:

Greetings form Germany,

You''re probably shadowing rack''s own request.rb

Hi Fred,

thanks for your response!
Can you give me some hints where I can read more absout filenames
which I should avoid? Or how to determine such a thing. This was a
pain for a couple of hours to find out!

Regards,
Klaus
