C#中的Url重写技术

public class UrlRewrite : IHttpHandler
{
public UrlRewrite()
{ }

#region IHttpHandler Members

public bool IsReusable
{
get { return true; }
}

public void ProcessRequest(HttpContext context)
{
try
{
string url = context.Request.Path.ToLower();
//处理url......

context.Response.WriteFile(url);
}
catch
{
context.Response.Write("文件不存在");
}
}

#endregion
}

<httpHandlers>
<add verb="*" path="*.html" type="yzzHttp.UrlRewrite" />
</httpHandlers>
