    // View the request that would be sent if SynchronousRequest is called.
    // The HTTP request will be a GET that looks like this:
    // 
    //     GET /watch?v=fAZdTchQePc&t=45s HTTP/1.1
    //     Host: domain
    // 
    // Note: The HOST header will automatically get filled in with the actual domain when SynchronousRequest is called.

    // We can add additional params

    // Now examine the request that would be sent
    // 
    //     GET /watch?v=fAZdTchQePc&t=45s&artist=Richard%20Bona&musicType=Jazz&festival=Estival%20Jazz%20Lugano&year=2008 HTTP/1.1

    // What happens if we change the request from a GET to a POST?
    req.put_HttpVerb(L"POST");
    // The request will now look like this:
    // 
    //    POST /watch HTTP/1.1
    //    Host: domain
    //    Content-Length: 93
