請問一下各位大大. 小弟最近在調整我的 PROXY server 但是有個問題 小第一直無法理解. 照理說.我設定 PROXY 連線. 第一次 因為 PROXY內沒有資料 他到外部去抓 再來應該就是直接回給使用者 之前抓的資料了 但是 我測試了2個網站 發現 以下2個情形. 1.http://taiwan.nba.com --看來似乎有使用到 cache FreeBSD -root-:http_ping -c 10 -i 2 -proxy proxy:8080 http://taiwan.nba.com 61720 bytes from http://taiwan.nba.com: 446.678 ms (0.366c/439.419r/6.893d) 61720 bytes from http://taiwan.nba.com: 21.316 ms (0.398c/13.801r/7.117d) 61720 bytes from http://taiwan.nba.com: 12.151 ms (0.401c/5.063r/6.687d) 61720 bytes from http://taiwan.nba.com: 20.897 ms (0.443c/13.748r/6.706d) 61720 bytes from http://taiwan.nba.com: 26.035 ms (0.315c/15.723r/9.997d) 61720 bytes from http://taiwan.nba.com: 45.725 ms (0.352c/10.849r/34.524d) 61720 bytes from http://taiwan.nba.com: 23.175 ms (0.34c/3.994r/18.841d) 61720 bytes from http://taiwan.nba.com: 23.202 ms (0.368c/13.35r/9.484d) 61720 bytes from http://taiwan.nba.com: 18.466 ms (0.361c/11.34r/6.765d) 61720 bytes from http://taiwan.nba.com: 52.222 ms (0.382c/12.569r/39.271d) --- http://taiwan.nba.com http_ping statistics --- 10 fetches started, 10 completed (100%), 0 failures (0%), 0 timeouts (0%) total min/avg/max = 12.151/68.9867/446.678 ms connect min/avg/max = 0.315/0.3726/0.443 ms response min/avg/max = 3.994/53.9856/439.419 ms data min/avg/max = 6.687/14.6285/39.271 ms 2.http://www.berkeley.edu --看來似乎沒有使用到 cache FreeBSD -root-:http_ping -c 10 -i 2 -proxy proxy:8080 http://www.berkeley.edu 21695 bytes from http://www.berkeley.edu: 625.539 ms (0.319c/314.987r/310.233d) 21695 bytes from http://www.berkeley.edu: 649.734 ms (0.341c/326.974r/322.419d) 21695 bytes from http://www.berkeley.edu: 650.345 ms (0.28c/327.712r/322.353d) 21695 bytes from http://www.berkeley.edu: 626.176 ms (0.341c/315.58r/310.255d) 21695 bytes from http://www.berkeley.edu: 627.871 ms (0.419c/316.5r/310.952d) 21695 bytes from http://www.berkeley.edu: 650.299 ms (0.358c/327.224r/322.717d) 21695 bytes from http://www.berkeley.edu: 626.325 ms (0.443c/315.453r/310.429d) 21695 bytes from http://www.berkeley.edu: 651.04 ms (0.387c/328.232r/322.421d) 21695 bytes from http://www.berkeley.edu: 650.467 ms (0.464c/327.452r/322.551d) 21695 bytes from http://www.berkeley.edu: 650.768 ms (0.476c/327.597r/322.695d) --- http://www.berkeley.edu http_ping statistics --- 10 fetches started, 10 completed (100%), 0 failures (0%), 0 timeouts (0%) total min/avg/max = 625.539/640.856/651.04 ms connect min/avg/max = 0.28/0.3828/0.476 ms response min/avg/max = 314.987/322.771/328.232 ms data min/avg/max = 310.233/317.703/322.717 ms 以上2個狀況. 是先後測試的. 我也確定 cache 的硬碟空間 是有空間的. 但是 為什麼 到很多地方去的時候 他並不會使用 cache 呢? 照理說 第一次到 外面去抓 後面那幾次 不是應該 直接把cache的資料回給使用者嗎?? --
