For example, the Front-Ends don’t have the knowledge of which infrastructure resources are used to store the cache data and what the topology of that infrastructure is.

This method tracks data changes by extracting metadata from update or delete queries or from within SQL comments.
Scale Arc’s auto cache invalidation feature uses the transparent No SQL technology by extracting metadata from the query and tagging the cache objects used to associate cache entries with invalidation queries.
In each case, you can invalidate for all hostnames or for just one hostname.
A cache is a component that stores data so future requests for that data can be served faster.
Therefore, all the other servers will have to do another access to the data store to fetch the same data again.
A distributed cache, however, stores the cached data on other infrastructure resources and manages it in a synchronized fashion, making the same cached data remotely available to all the Front-Ends in a transparent way.
We also check that the application automatically logs out a user when that user has been idle for a certain amount of time, and that no sensitive data remains stored in the browser cache.
The end of a web session is usually triggered by one of the following two events: Both cases must be implemented carefully, in order to avoid introducing weaknesses that could be exploited by an attacker to gain unauthorized access.
The Scale Arc analytics UI helps identify the queries that belong to the same table and access the same column.
Users can then add invalidation patterns to an invalidation group that manipulates the same table and column.
You cannot, nor should you want to ever turn it off. The system cache is used by Statamic and addons to store data for defined lengths of time, much like sessions or cookies might do on the browser side. As an example, the Image Transform feature uses this cache to store all the manipulated images and their various sizes.
