BackForwardCacheEnabled

When enabled the BackForwardCache feature allows the use of the back-forward cache. When navigating away from a page, its current state (document tree, script, etc.) may be preserved in the back-forward cache. If the browser navigates back to the page, the page may be restored from the back-forward cache and displayed in the state it was in before being cached. This feature might cause issues for some websites that do not expect this caching. In particular, some websites depend on the "unload" event being dispatched when the browser navigates away from the page. The "unload" event will not be dispatched if the page enters the back-forward cache. If this policy is set to enabled or not set, the BackForwardCache feature will be enabled. If this policy is set to disabled then the feature will be force disabled.
