Apache中URL Rewrite技術的實作

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動态形式的網頁檔案能夠被GOOGLE等搜尋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：比如在背景用PHP程式将原來的檔案改成HTM内容；采用Apache的Path_Info技術，但覺得還是不夠強大，是以決定采用Apache中的URL Rewrite技術來試用一下。

很早就注意到它了，但一直不知道怎麼實作，今天咬咬牙，翻了N篇有關的文章，終于實作了一些基本的功能：

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

options followsymlinks

然後再在此目錄下建立一個.htacess檔案，它的内容如下：

rewriteengine on

rewritebase /websamples/urlrewrite/

RewriteRule news/(/d+)/.html news/.php/?id=$1 [N,L]

這樣就實作了将http://localhost/news/1000.html 解析為 http://localhost/news.php?id=1000的功能
