URL重写

/// <summary>
/// 当一个请求过来的时候会被调用,html静态文件是iis直接把文件给到浏览器,不经过asp.net引擎处理
/// 所以不会调用Application_BeginRequest方法
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void Application_BeginRequest(object sender, EventArgs e)
{
    File.AppendAllText(@"c:\1.txt", DateTime.Now + "Application_BeginRequest" 
        + Context.Request.RawUrl + "\r\n");
    //Context.RewritePath("HtmlPage1.html");
    //url重写
    Match match = Regex.Match(Context.Request.Path, @"^/UrlWrite\-(\d+)\.ashx$");
