        @high_voltage wow that's different. I had issues where I needed to clear the cache before the traffic would flow again, almost like a container was in the cache.

            @kom sorry I thought you wanted to see a Windows 10 update run that was cached.

              @jonathanlee Perhaps four years ago I did. I don't remember since it's been four years. I don't even use squid anymore. It's completely useless other than as a base for squidguard URL filtering.

                @kom I respectfully disagree with "useless", I use it for HTTPS cache anti-virus scanning of HTTPS websites and HTTP. Dynamic caching, URL filtering, and blocking. Don't get me wrong it is rather complicated to understand, however the vast abilities that it has to customize a network environment by need is what sets it apart. It can do many things. It is just a challenge to learn. It has also protected my system from many hidden issues that Clam AV stops and reports with HTTPS alongside pup detection as well as generates clear reports. It's Mirrored Analytics down to a granular level.

                    @dmalick You can use the latest here https://github.com/mmd123/squid-cache-dynamic_refresh-list

                    Yes it works with the latest squid

                        @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stored, miss means its stored as of now because it was never stored yet, refresh means dynamic based refresh that is out of date or expired timer.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.
