How can i make so that my unity web players stores the game cache memory ? It take like 2-4min to load my game each time. My friends unity save the cache and he loads for like 10 sec.
I am using firefox, and so does he.

Did u try that?

WebPlayer users may disable Caching for all WebPlayer applications by right-clicking on the WebPlayer content, selecting “Setup…”, and checking the ‘Disable all caching’ checkbox. If caching is disabled, WWW.LoadFromCacheOrDownload() will continue to function, but will never cache downloaded AssetBundles. Caching is always enabled for PC/Mac Standalone and iOS/Android player builds.
if (!Caching.enabled)
