Add extra data to RefreshAuthorization() method call of WebServerClient

[sam-leung]

i'm trying to use the WebServerClient class of the DotNetOpenAuth to refresh my token. is there a way to pass additional data to the "RefreshAuthorization()" method call or to the request package/payload? i need to pass additional data to the server when requesting for a refresh of the token.

so i have currently:

string clientId = "something";
string clientSecret = "blah";

AuthorizationServerDescription authServer = new AuthorizationServerDescription()
{
    TokenEndpoint = new Uri(TOKEN_ENDPOINT),
    AuthorizationEndpoint = new Uri(AUTHZ_ENDPOINT),
};

var client = new WebServerClient( authServer, clientId, clientSecret );
IAuthorizationState state = client.ExchangeUserCredentialForToken( "username", "password" );
client.RefreshAuthorization(state);

thank you very much for your help
