Subject: IOWA Question (long because of code snippets)

Hello-

I've been looking through the archives of this list some, but I'm feel 
like I'm missing some critical (and probably simple) piece of 
information. I'm trying to setup a page in IOWA where the URL contains 
some a piece of information needed to render the page.

Basically, I want to take URLs like:

http://localhost:2000/details/FOO/

And have my application render a page using FOO as a variable. My 
problem is that I'm using IOWA Webrick and it seems that IOWA is just 
passing on processing this. However, if I just go to 
http://localhost:2000/details/FOO/, it's working correctly. Maybe I'm 
using the mapfile wrong? Or do I just not need the mapfile at all?

My MyApplication class looks like this:

require 'iowa_webrick'

class MyApplication < Iowa::Application
     def initialize(*args)
         @@cachedSession = 10
         @mapfile = 'mapfile.cnf'
         super
     end
end

Iowa.startDaemon('app.cnf')
Iowa.run

And my Main.iwa looks like (which I found on this list):

class Main < Iowa::Component
     def setup
         $stderr.puts session.context.request.inspect
         asin = File.basename(session.context.request.uri)
         dispatch_page = page_named('Details')
         dispatch_page.parameter = parameter
         dispatch_context = Iowa::Context.new(session.context.request,
                                              session.context.response)
         dispatch_context.sessionID = session.context.sessionID
         dispatch_context.requestID = session.requestCount
         dispatch_page.handleResponse(dispatch_context)
         session.currentPage = dispatch_page.dup
     end
end

And finally, my mapfile.cnf has:

/: Details
/details: Details
/details/: Details
[
Which is obviously mostly useless, I just was trying a bunch of 
different things.

Thanks for your help.

Ben
