/**
* This event is dispatched just before the final page cache identifier is created,
* that is used to get() - and later set(), if needed and allowed - the page cache row.
*
* The event retrieves all current arguments that will be part of the identifier
* calculation and allows to add further arguments in case page caches need
* to be more specific.
*
* This event can be helpful in various scenarios, for example to implement
* proper page caching in A/B testing.
*
* Note this event is *always* dispatched, even in fully cached page scenarios,
* if an outer middleware did not return early (for instance due to permission issues).
