Is it possible to disable following redirects in OkHttp 2.0?

Yes it is possible in version 2.3.0

final OkHttpClient client = new OkHttpClient();
client.setFollowRedirects(false);

For 3.x

OkHttpClient client = new OkHttpClient().newBuilder()
                                            .followRedirects(false)
                                            .followSslRedirects(false)
                                            .build();
