1、首先請進入以下網(wǎng)址 http://www.helicontech.com/download/，下載免費版的ISAPI_Rewrite組件：ISAPI_Rewrite Lite ( freeware )。如果您僅僅是測試用途使用這個就足夠了，如果您是商業(yè)應用建議您購買完整版的 ISAPI_Rewrite Full。

2、點擊下載到本地的文件 isapi_rwl_x86_0064.msi （該文件名和您下載的版本有關）(注意下載的時候請看清你的系統(tǒng)的環(huán)境下載，別下載錯了啊，親．)
進行安裝，安裝成功之后進入安裝目錄（默認在C:/Program Files/Helicon/ISAPI_Rewrite）找到httpd.ini文件，點擊右鍵將文件只讀屬性去掉。然后進入： 開始菜單->程序->Helicon->ISAPI_Rewrite->httpd.ini，點擊打開 httpd.ini 文件。
（注：也可以不用下載安裝，本站提供此文件的下載，下載請移步《偽靜態(tài)重寫模塊rewrite.dll及httpd.conf下載》）
3、復制下面的內容到httpd.ini文件
4、在IIS的Isapi上添加這個篩選器, 篩選器名稱Rewrite,可執(zhí)行文件選擇 C:\Program Files\Helicon\ISAPI_Rewrite\ISAPI_Rewrite.dll

上面的篩選器名稱可以隨便輸入，自己認識即可，然后可執(zhí)行文件，找到你對應的rewrite.dll文件，然后確定即可；
