IIS6默認(rèn)情況下沒(méi)有開(kāi)啟GZIP功能，需要我們手動(dòng)配置，但他又沒(méi)提供圖形化配置功能，所以呀，像我這樣的技術(shù)人才，都沒(méi)考慮過(guò)使用他，昨天突然看到這個(gè)想到，也許對(duì)我有用，但從網(wǎng)上找了找，都是一堆手工操作方法，非常麻煩呀，不過(guò)以前研究過(guò)IIS的配置文件：C:\WINDOWS\system32\inetsrv\MetaBase.xml，所以呀，我知道只要是IIS的功能就可以通過(guò)修改這個(gè)文件來(lái)完成，所以呢，就對(duì)這個(gè)文件下手吧，根據(jù)網(wǎng)上提供的修改的地方，在網(wǎng)上搜索了一圈，找到一個(gè)類(lèi)似ClickOnce 的東西，呵呵，我找的就是這個(gè)，所有操作都一鍵到位，只要執(zhí)行一段VBS或CMD就配置好了，呵呵。

        使用Gzip壓縮會(huì)增大服務(wù)器CPU的使用率但可以通過(guò)壓縮而減少服務(wù)器向客戶端發(fā)送的數(shù)據(jù),若使用了Gzip壓縮IIS在向客戶端發(fā)送數(shù)據(jù)時(shí)會(huì)自動(dòng)檢測(cè)，如果客戶端瀏覽器支持IE6.0,firefox Gzip,則使用Gzip壓縮后再傳送數(shù)據(jù)，如果不支持，則使用常規(guī)方式發(fā)送。

        所以，總結(jié)下他的優(yōu)缺點(diǎn)，優(yōu)：壓縮傳輸，速度一般提高2倍。缺：CPU占用會(huì)有所提高，不過(guò)通過(guò)我的一點(diǎn)分析，GZIP只是在訪問(wèn)一個(gè)頁(yè)時(shí)才會(huì)進(jìn)行壓縮，下次如果網(wǎng)頁(yè)沒(méi)有變動(dòng)是不會(huì)壓縮的，除非是使用壓縮動(dòng)態(tài)文件，這得實(shí)時(shí)的去壓縮。
