This is late, I think but I put it here for notes for anyone else facing the issue. Here are my code samples (this is for Glide v4):

BaseGlideUrlLoader module:

private static class HeaderedLoader extends BaseGlideUrlLoader {

    public static final Headers HEADERS = new LazyHeaders.Builder()
            .addHeader("Referer", UserSingleton.getInstance().getBaseUrl())
            .build();

    public HeaderedLoader(ModelLoader concreteLoader) {
        super(concreteLoader);
    }

    @Override public boolean handles(@NonNull String model) {
        return true;
    }

    @Override protected String getUrl(String model, int width, int height, Options options) {
        return model;
    }

    @Override protected Headers getHeaders(String model, int width, int height, Options options) {
        return HEADERS;
    }

    public static class Factory implements ModelLoaderFactory {

        @Override public @NonNull ModelLoader build(
                @NonNull MultiModelLoaderFactory multiFactory) {
            return new HeaderedLoader(multiFactory.build(GlideUrl.class, InputStream.class));
        }

        @Override public void teardown() { /* nothing to free */ }
    }
}

Add the HeaderLoader class in the AppGlideModule.

@Override
public void registerComponents(@NonNull Context context, @NonNull Glide glide, @NonNull Registry registry) {
    super.registerComponents(context, glide, registry);

    registry.replace(GlideUrl.class, InputStream.class,
            new OkHttpUrlLoader.Factory(CustomOkHttpsClient.getTrustedOkHttpClient()
            ));

    // override default loader with one that attaches headers
    registry.replace(String.class, InputStream.class, new HeaderedLoader.Factory());
}

My solution is based on link provided here https://github.com/TWiStErRob/glide-support/commit/b357427363c28a82495097ec862b82acdf3b4357

The original issue is discussed here https://github.com/bumptech/glide/issues/471
