Question Caching a Assetbundle from bytes[]?

I am using a .Net socket to download assetbundles as bytes[] and load the Assetbundle object to the scene.

I am having trouble understanding if it is possible to cache a Assetbundle object manually?

The socket sends a filename with the bytes so I do have a unique filename I can use to identify the cache,

But I am completely lost how to create a cache from a Assetbundle object?

Is there any way to cache a assetbundle where I have downloaded the bytes and a filename?
