      question 1 : why it always view it "Number of clients accessing cache: 0" ?
      question 2 : from my squid.log file. Before installing lusca_cache, youtube log was

      http://v13.lscache8.c.youtube.com/videoplayback?

      after installing lusca_cache

      http://v13.lscache8.c.youtube.com/videoplayback?ip=0.0.0.0&sparams=id%2Cexpire%2Cip%2Cipbits%2Citag%2Calgorithm%2Cburst%2Cfactor%2Coc%3AU0dWRVdNUl9FSkNNNl9PR1ZF&fexp=906204&algorithm=throttle-factor&itag=34&ipbits=0&burst=40&sver=3&expire=1270724400&key=yt1&signature=C7E3966A1CE37924992959454375B87C83C2AB46.A057390D20A4A26EA8E046A7FB46EF22FADB26B3&factor=1.25&id=924027d0fae57447

      is this means it cached corrrectly?

        because client_db off… updated changed to on
        xml reinstall(Reinstall this package's GUI components) will do if you don't want to edit /usr/local/etc/squid/include.conf

        question 2 about access.log

        because strip_query_terms off… for security reason's you can turn this on. my default is off to track down this patterns.

            by the way I haven't used videocache. AFAIK videocache is using url_rewrite.
            to monitor you can tail your access log with some grep or use your broweser.
            Using Developer tools in google chrome. you can see X-Cache:HIT from pfsense at header.
            With firefox you can use firebug plugin.
