As I was updating the tests, I found that data cannot currently be sent with the DELETE method.  When doing further research, I wasn't sure whether this should be allowed or not.  The test client accepts a data parameter for DELETE, but the HTTP spec suggests that you shouldn't expect data, like you can for a POST: http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html#sec9.7 If we want to I can figure out how to actually get data through the chain.  Otherwise I can update the documentation to reflect the changes instead.
