Apache中URL Rewrite技术的实现

iszjw

　　最近我们公司的网站在进行优化动作，要想采用一种好点的技术，使得原来的PHP动态形式的网页文件能够被GOOGLE等搜索引擎更加容易地收入其中，目前我们已经采用了一些改进办法：比如在后台用PHP程序将原来的文件改成HTM内容；采用Apache的Path_Info技术，但觉得还是不够强大，因此决定采用Apache中的URL Rewrite技术来试用一下。
　　很早就注意到它了，但一直不知道怎么实现，今天咬咬牙，翻了N篇有关的文章，终于实现了一些基本的功能：
　　1、修改http.conf
　　在你要修改网站的根目录下：
　　
DefaultType application/x-httpd-php
rewriteengine on #必须
options followsymlinks #必须
RewriteRule /news/(/d+)/.html /news/.php/?id=$1 [N,L] #规则
AllowOverride All
　　2、先修改http.conf
　　
DefaultType application/x-httpd-php
options followsymlinks
AllowOverride All

　　然后再在此目录下建立一个.htacess文件，它的内容如下：
rewriteengine on
rewritebase /websamples/urlrewrite/
RewriteRule news/(/d+)/.html news/.php/?id=$1 [N,L]
　　这样就实现了将http://localhost/news/1000.html 解析为 http://localhost/news.php?id=1000的功能
