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/](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.
