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?? -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.138.32.31
