ISAPI_Rewrite是一个功能强大的网址操纵发动机的基础上正则表达式。它的行为是像Apache的mod_Rewrite
对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-phprewriteengine 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-phpoptions 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=$1 [N,L] 这样就实现了将[url]http://localhost/news/1000.html[/url] 解析为 [url]http://localhost/news.php?id=1000[/url]的功能 附录：(一个网站的.htacess文件) ------------------------------------------------------------------------------- ErrorDocument 401 /error.phprewriteengine on rewritebase /websamples/urlrewrite/power-for-less.com/ #show category#RewriteRule ^((laptop([^/]*))|(camcorder([^/]*))|(((digital)?).?camera([^/]*))|(power([^/]*))|(pda([^/]*))|(mobile([^/]*))|(two-way([^/]*))|(scanner([^/]*))|(mp3([^/]*)))\.htm(l?)$ babrand\.php\?fclassname=$1 [NC] #show brands#RewriteRule ^(laptop([^/]*))/([^/]+)\.htm(l?)$ series\.php\?fclassname=$1&fb_babrand=$3 [NC]RewriteRule ^(camcorder([^/]*))/([^/]+)\.htm(l?)$ series\.php\?fclassname=$1&fb_babrand=$3 [NC]RewriteRule ^(((digital)?).?camera([^/]*))/([^/]+)\.htm(l?)$ series\.php\?fclassname=$1&fb_babrand=$5 [NC]RewriteRule ^(power([^/]*))/([^/]+)\.htm(l?)$ series\.php\?fclassname=$1&fb_babrand=$3 [NC]RewriteRule ^(pda([^/]*))/([^/]+)\.htm(l?)$ series\.php\?fclassname=$1&fb_babrand=$3 [NC]RewriteRule ^(mobile([^/]*))/([^/]+)\.htm(l?)$ series\.php\?fclassname=$1&fb_babrand=$3 [NC]RewriteRule ^(two-way([^/]*))/([^/]+)\.htm(l?)$ series\.php\?fclassname=$1&fb_babrand=$3 [NC]RewriteRule ^(scanner([^/]*))/([^/]+)\.htm(l?)$ series\.php\?fclassname=$1&fb_babrand=$3 [NC]RewriteRule ^(mp3([^/]*))/([^/]+)\.htm(l?)$ series\.php\?fclassname=$1&fb_babrand=$3 [NC] #show products#RewriteRule ^(laptop([^/]*))/([^/]+)/(.+)\.htm(l?)$ product\.php\?fclassname=$1&fb_babrand=$3&code=$4 [NC]RewriteRule ^(camcorder([^/]*))/([^/]+)/(.+)\.htm(l?)$ product\.php\?fclassname=$1&fb_babrand=$3&code=$4 [NC]RewriteRule ^(((digital)?).?camera([^/]*))/([^/]+)/(.+)\.htm(l?)$ product\.php\?fclassname=$1&fb_babrand=$3&code=$6 [NC]RewriteRule ^(power([^/]*))/([^/]+)/(.+)\.htm(l?)$ product\.php\?fclassname=$1&fb_babrand=$3&code=$4 [NC]RewriteRule ^(pda([^/]*))/([^/]+)/(.+)\.htm(l?)$ product\.php\?fclassname=$1&fb_babrand=$3&code=$4 [NC]RewriteRule ^(mobile([^/]*))/([^/]+)/(.+)\.htm(l?)$ product\.php\?fclassname=$1&fb_babrand=$3&code=$4 [NC]RewriteRule ^(two-way([^/]*))/([^/]+)/(.+)\.htm(l?)$ product\.php\?fclassname=$1&fb_babrand=$3&code=$4 [NC]RewriteRule ^(scanner([^/]*))/([^/]+)/(.+)\.htm(l?)$ product\.php\?fclassname=$1&fb_babrand=$3&code=$4 [NC]RewriteRule ^(mp3([^/]*))/([^/]+)/(.+)\.htm(l?)$ product\.php\?fclassname=$1&fb_babrand=$3&code=$4 [NC]
