            @dmalick keep in mind that sometimes if changes in a website are very small it will still load old information if you use ssl intercept and have it set up to cache https. I have had a issue with a time card that would not load a new line because the watermark was to low to require a refresh, however on a different machine it would see the new time card. Just be aware that things are still a work in progress.

                    @dmalick what made you use 25 for the SSL children? I just use the default of 5, maybe I should increase mine.

                          @dmalick cdn stands for content delivery network, are you using a steaming service? Example Hulu Disney plus or Amazon prime, I have the proxy set to not cache these because it's a steaming service.

                            @dmalick Hit means its already stored, miss means its stored as of now because it was never stored yet, refresh means dynamic based refresh that is out of date or expired timer. Do a quick search on the specifics, you will never have 100 percent hits.
