Glide Image request : Does downloadOnly check the cache before downloading only?

I am making a request like below, but i want to know if downloadOnly checks the cache for the image first?

FutureTarget<File> future = Glide.with(applicationContext)
    .load(yourUrl)
    .downloadOnly(500, 500);
File cacheFile = future.get();

My main issue is that the image in yourUrl is already loaded in the cache, and i need a synchronous way to retrieve the image from the cache in a background thread.

The code above works, but i need to know if there is a cache check before downloadOnly. Thanks.
