Using a CacheFilter allows nevisProxy to serve requests directly by itself, without requesting the data from your application. This reduces the requests your application server needs to serve (CPU usage on the back end). A CacheFilter may also be assigned in front of the proxy's input validation filters to omit repeated validation of the same content. A cache filter may be configured to use either memory or the disk to store cached content.
Pay attention to the fact that you should not assign a CacheFilter to personalized content!
