 twisted.web.client.Agent automatically converts request headers to
 canonical form (uSeR-AgEnt becomes User-Agent), this means that we are
 unable to use it for our header field manipulation test.

 I would suggest going for the path of subclassing http.HTTPClient and
 drawing inspiration from HTTPPageGetter, in particular I would look at the
 methods connectionMade and of HTTPPageGetter.

 This should then be a flag that can be passed to the HTTP test template
 that allows us to perform HTTP requests without this mangling going on.
