// TODO: RFC 3875 isn't clear if only GET is supported, but it
// suggests so: "Note that any message-body attached to the
// request (such as for a POST request) may not be available
// to the resource that is the target of the redirect." We
// should do some tests against Apache to see how it handles
// POST, HEAD, etc. Does the internal redirect get the same
// method or just GET? What about incoming headers?
// (e.g. Cookies) Which headers, if any, are copied into the
// second request?
