最近我們公司的網站在進行優化動作，要想采用一種好點的技術，使得原來的PHP動態形式的網頁文件能夠被GOOGLE等搜索引擎更加容易地收入其中，目前我們已經采用了一些改進辦法：比如在后臺用PHP程序將原來的文件改成HTM內容；采用Apache的Path_Info技術，但覺得還是不夠強大，因此決定采用Apache中的URL Rewrite技術來試用一下。
很早就注意到它了，但一直不知道怎么實現，今天咬咬牙，翻了N篇有關的文章，終于實現了一些基本的功能：
1、修改http.conf
在你要修改網站的根目錄下：
DefaultType application/x-httpd-php
rewriteengine on #必須
options followsymlinks #必須
RewriteRule /news/(\d+)\.html /news\.php\?id=$1 [N,L] #規則
AllowOverride All
2、先修改http.conf
DefaultType application/x-httpd-php
options followsymlinks
AllowOverride All
然后再在此目錄下建立一個.htacess文件，它的內容如下：
rewriteengine on
rewritebase /websamples/urlrewrite/
RewriteRule news/(\d+)\.html news\.php\?id=$1 [N,L]
這樣就實現了將http://localhost/news/1000.html 解析為 http://localhost/news.php?id=1000的功能
