        { }        #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
