Driver selection does not work when using WEBrick server

                 Key: DTACLOUD-34
                 URL: https://issues.apache.org/jira/browse/DTACLOUD-34
             Project: DeltaCloud
          Issue Type: Bug
          Components: Server
         Environment: Fedora 14, deltacloud git-svn-id: 
https://svn.apache.org/repos/asf/incubator/deltacloud/trunk@1097646

One of the new features of deltacloud 0.3.0 is the ability to switch backend 
drivers on a per-request basis.  One of the ways to do this is to create a URL 
like: http://localhost:3001/api;driver=mock.  When using the thin webserver, 
this invocation works just fine, and you get the output from the mock driver.  
However, when using the WEBrick server, this does not work and you get an error 
page that says "Sinatra doesn't know this ditty" (this generally means a 404).  
The relevant part of the deltacloudd log looks like:

127.0.0.1 - - [29/Apr/2011 09:04:03] "GET 
http://localhost:3001/api?api[driver]=mock HTTP/1.1" 404 433 0.0124

That GET request is actually wrong; it should be something like "GET 
/api?api[driver]=mock", not the full URL.  This observation led me to a patch 
(which I will attach), which seems to improve the situation.  However, it 
doesn't completely solve the problem, as even with this patch applied I still 
cannot make driver selection work.
