使用URLRewriter实现URL重写
优点
1）隐藏真实URL，提高安全性
2）更加友好的URL，好记（看博客园就行知道啦）
3）便于搜素引擎收录
.........
可能的缺点
使用URL重写可能导致：
1）图片路径的问题
2）CSS路径的问题
3）性能问题
.........
先下载DLL包,附带了源码的.
download.microsoft.com/download/0/4/6/0463611e-a3f9-490d-a08c-877a83b797cf/MSDNURLRewriting.msi
URLRewriter.dll和ActionlessForm.dll
或者只使用DLL 本人已经上传:https://files.cnblogs.com/yun_shuai/URLRewriter.rar 含有上面2个DLL
使用方法 :WEB项目中添加引用
webconfig中配置:
1 <configSections> 节点中增加:
<section name="RewriterConfig" type="URLRewriter.Config.RewriterConfigSerializerSectionHandler,URLRewriter"/>
2 <configuration>根节点中增加URL重写的配置: 可以使用正则表达式
<RewriterConfig>
<Rules>

<RewriterRule>
<LookFor>~/Products/Seafood\.aspx</LookFor>
<SendTo>~/ListProductsByCategory.aspx?CategoryID=8</SendTo>
</RewriterRule>
</Rules>
</RewriterConfig>
3 <httpModules> 增加
<add type="URLRewriter.ModuleRewriter, URLRewriter" name="ModuleRewriter" />
或者
<httpHandlers> 增加
<add verb="*" path="*.aspx" type="URLRewriter.RewriterFactoryHandler, URLRewriter" />
4 完成.
5 其他问题:
回发后真实路径再现:
1、将ActionlessForm.dll添加到项目的bin文件夹
2、在aspx网页的代码中加<%@ Register TagPrefix="RW" Namespace="ActionlessForm" Assembly="ActionlessForm" %>
3、然后将form标签改为RW:Form（注意开始和结束都要改），TagPrefix可以自定义
另外:DOTNET3.5 提供了 System.Web.Routing 命名空间
可以自己实现想要的URL重写.

从以上2篇文章地址可以看出,其服务器也使用了URL重写方式
