某墙尼妹，用个Response.Filter来解决StackExchange.Exceptional中google cdn的问题

某墙墙了古古路，一些开源的东东里用了古古路CDN，比如Exceptional,Opserver ,导致服务要么慢要么用不了

必须要替换之

Exceptional就只要用Response.Filter替换个页面了，因为自己维护个版本还要定期合并什么的，操心

 internal class ResponseStream : MemoryStream        {            #region ctor            private Stream Output { get; set; }            public HttpContextBase Context { get; set; }            /// <summary>            /// 页面输出的Stream Buffer            /// </summary>            public List<byte> BytesArray { get; set; }            public ResponseStream(HttpContextBase context)            {                Context = context;                Output = context.Response.Filter;                context.Response.BufferOutput = true;                context.Response.Buffer = true;                BytesArray = new List<byte>();            }            #endregion            public override void Write(byte[] buffer, int offset, int count)            {                if (Context.Response.ContentType != "text/html")                {                    Output.Write(buffer, offset, count);                    return;                }                BytesArray.AddRange(buffer);            }            public override void Close()            {                if (BytesArray.Count > 0)                    CloseByReplace();                Output.Close();                base.Close();            }            private void CloseByReplace()            {                var html = Encoding.UTF8.GetString(BytesArray.ToArray(), 0, BytesArray.Count);                var sb = new StringBuilder(html);                sb.Replace("//ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js", "http://libs.baidu.com/jquery/1.7.2/jquery.min.js");                var outputBytes = Encoding.UTF8.GetBytes(sb.ToString());                Output.Write(outputBytes, 0, outputBytes.Length);            }        }

Action对应的改为：

        public ActionResult Exceptions()        {            var context = System.Web.HttpContext.Current;            context.Response.Filter = new ResponseStream(HttpContext);            var page = new HandlerFactory().GetHandler(context, Request.RequestType, Request.Url.ToString(),                Request.PathInfo);            page.ProcessRequest(context);            return null;        }
