I am pretty happy to read the steps to follow for successful caching of Windows. Many of my problems got resolved with the help of www.studytonight.com/post/best-programming-languages-to-learn-in-2019 website which has big reputation in the world of student's help.

Resolution Note (2017.4.X):
1. You need to use `UnityWebRequestAssetBundle` since `WWW` isn't supported and doesn't save the correct cache path anymore due to an issue with it not using the correct hash. UWR does.
2. You have to unload their bundle before they can clear their cache. It can't work otherwise. That said there is an odd issue where if they've downloaded the bundle/cached it with UWR but not loaded it through the `DownloadHandlerAssetBundle.GetContent` API then `AssetBundle.UnloadAllAssetBundles(bool)` won't actually unload the bundle. They have to get the bundle from UWR and make sure it's unloaded.
3. You're giving the asset bundle name as a path `abm/examples/unitylogo` because that's the path from StreamingAssets down to their bundle on disk. You can't give that same path to `Caching.LiterallyAnyAPI` because it only caches based on the name itself (and the path of the cache of course), not any sort of given path.
