Subject: Implementig a XCAP web server:  Ebb and Rack ?

Hi, I plan to deploy a web server to implement a XCAP service (it's basically 
a web server which handles body with specific XML content). Some examples:

- The client requests a XML document (GET) so the server replies it in the 
body of the 200 OK.

- The client stores a XML document (PUT) in the server, so the server 
validates it and stores in a DB table.


There are a lot of web servers built in Ruby and I'm getting a bit crazy by 
tryting to choose one. I've read about Ebb web server (which seems to be very 
fast) and RACK (which seems to be a framework to build the application by 
receiving requests from the web service, Ebb in this case).

Unfortunatelly, by reading the doc of RACK (Ebb has no doc at all) I can't 
figure how to build the application:
  http://rack.rubyforge.org/doc/

RACK doc also talks about "middleware" (buff...) which annoy me even more. 
Anyhow I think that what I want to achieve doesn't require more middleware. 
But I would like to have some "get started" guidelines to work with RACK. For 
example, a ismple example:

A web server that receive a request and replies "200 OK" if the request URL is 
"/yes" and "404 Not Found" is the request URL is "/no".

Could I get some tips on how to build this simple example with Ebb and RACK?

Thanks a lot.
