怎么样在ASP.NET2.0中实现URL重写？
本文参考了网上已有代码，在此基础上进行了整理归纳，总结出在ASP.NET2.0环境下实现URL重写的行之有效的方法。如果转载，请注明出处：雪尘的专栏一、在网站中添加MyHttpModule类，代码如下：
usingSystem;usingSystem.Collections;usingSystem.Collections.Specialized;usingSystem.IO;usingSystem.Text;usingSystem.Text.RegularExpressions;usingSystem.Xml;usingSystem.Web;usingSystem.Web.UI;usingSystem.Web.Caching;namespaceUrlRewrite
