How does one know that cache is working?
Specifically, in the first two instances, cache front end and back end file store, is there a place on my server where the files are kept so that I can confirm that things are working? Would the config throw an error if it was not?
Also, is file back end store really any better than the built-in Linux (and other nix) automatic caching of virtually all served data?
Someone should write up a white paper on ALL these items!
Any info welcome!
