啟用IIS6的GZIP功能，提高網(wǎng)站打開速度，減少帶寬占用

IIS6默認情況下沒有開啟GZIP功能，需要我們手動配置，但他又沒提供圖形化配置功能

所以呀，像我這樣的技術(shù)人才，都沒考慮過使用他，昨天突然看到這個想到，也許對我有用，但從網(wǎng)上找了找，都是一堆手工操作方法，非常麻煩呀，不過以前研究過IIS的配置文件：C:\WINDOWS\system32\inetsrv\MetaBase.xml，所以呀，我知道只要是IIS的功能就可以通過修改這個文件來完成，所以呢，就對這個文件下手吧，根據(jù)網(wǎng)上提供的修改的地方，在網(wǎng)上搜索了一圈，找到一個類似ClickOnce 的東西，呵呵，我找的就是這個，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壓縮會增大服務器CPU的使用率但可以通過壓縮而減少服務器向客戶端發(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)時會自動檢測，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，優(yōu)：壓縮傳輸，速度一般提高2倍。缺：CPU占用會有所提高，不過通過我的一點分析，GZIP只是在訪問一個頁時才會進行壓縮，下次如果網(wǎng)頁沒有變動是不會壓縮的，除非是使用壓縮動態(tài)文件，這得實時的去壓縮。
