      @Valeriy:

      Forget about video caching…
      Most video services push content via HTTPS, which we cannt cache.

      If you really need to have some video supplied to your users, then just download it and make is available via PLEX service, for instance or just regular network file system (SMB, NFS, etc.)

      Unless…You do MITM inspection.

      I do not know the MITM inspection.

      I'm currently having issues with it after the latest Squid update, unsure as to why. However, you can do MITM inspection by enabling SSL filtering and deploying out a CA certificate to your clients.

                  Doesn't apple block MITM using certificate pinning? Since their app store is over HTTPS.

                    @Valeriy:

                    KOM was right, in fact it was not working properly. Also, the results of bare counting of MISSes/HITs from not fully populated cache was not good measurement. Right now, any windowsupdate downloaded file (even partial) is fetched from cache, verified manually and monitored in access.log.

                    Few days ago I have made some improvements to utilize store_rewrite module.
                    They were tested, as suggested above by KOM, successfully.

                    Indeed, some of WU were not cached properly since they were received from different CDN hosts.

                    Config files are below (squid.conf is only part that is related to this issue)

                    Apple and Symantec updates are cached well, too.

                    Steam/Xbox (cs.steampowered.com / llnwd.net respective CDN) are not confirmed yet.

                    The rest of refresh patterns and URL rewrites are still in experimental mode. Needs a lot of testing and research in order to make it done properly.

                    Attached is screenshot from Lightsquid, you can clearly see changes after 3rd of March.

                    P.S. Questions:

                    • not quite sure if I need to list all possible domains under acl dstdomain directive, or just first level domain will be good enough?

                    Comments:

                    • I have total 1.3TB of swap available and 32GB on server running Pfsense+Squid+SquidGuard+Snort+PfBlocker. Configuration is optimized for ~2000 hosts on LAN.

                    Current byte/hit rate is 20-45%

                    May I know.
                    1. Is it just copy CODE in Table 1(/usr/local/etc/squid/squid.conf) and paste to "Custom refresh_patterns" of squid on Pfsense ? Or any other changes need on Table 1.
                    2. How useful Table 2(/usr/local/etc/squid/updatesites.txt ) and Table 3(/usr/local/etc/squid/storeid_rewrite.conf)? Need to insert these tables on Table 1? If needed, guide me pls(I am Beginner)
                    My aim is to get steam update cache(dota2)

                        Hi,

                        Sorry for the stupid question..
                        But where does the following code goes:

                        #new refresh patterns 3
acl Windows_Update dstdomain windowsupdate.microsoft.com
acl Windows_Update dstdomain .update.microsoft.com
acl Windows_Update dstdomain download.windowsupdate.com
acl Windows_Update dstdomain www.download.windowsupdate.com
acl Windows_Update dstdomain au.download.windowsupdate.com
acl Windows_Update dstdomain bg.v4.pr.dl.ws.microsoft.com

                        Does it go to the ACLs tab?
                        Is it white list or does it go in local cache -> Custom refresh_patterns

                        Thank you

                                        Facebook is a heavy traffic site for me which I could probably benefit from caching. I'm curious what the ip is?

                                          Just a question has anyone found an Improvement in there hit rate using this custom refresh pattern?

                                          I wounder if there is a simple refresh_pattern * that sates cache all instead of defining all these file types and domains.

                                          Never Fear, A Geek is Here!

                                            A simple refresh pattern will break HTTP heavily.
                                            You  can increase number of minutes in default pattern and see yourself.
