Glide Cache does not persist when app is killed : <p>I'm monitoring my web calls with Charles.</p>

<p>I have a GlideModule changing cache folder by overriding applyOption(...) like this : </p>

<pre><code>    @Override
public void applyOptions(Context context, GlideBuilder builder) {
    builder.setDiskCache(
            new InternalCacheDiskCacheFactory(context, "/media/", 1500000)
    );
}
</code></pre>

<p>Then, I do my Glide images loads and the cache works just fine while I'm in the app. Here is an example : </p>

<pre><code>Glide.with(this)
            .load("http://www.wired.com/wp-content/uploads/2015/09/google-logo.jpg")
            .into(mImageView);
</code></pre>

<p>Only the first call make a web call and then it use cache to retrieve it.
However, if I kill the app then relaunch it, instead of continuing to use the cache, the app make a new web call.
Isn't the cache supposed to be persistent inside the Internal storage ? </p>
