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 > )

                    CloseByReplace();

                Output.Close();

                base.Close();

            }

            private void CloseByReplace()

            {

                var html = Encoding.UTF8.GetString(BytesArray.ToArray(), , BytesArray.Count);

                var sb = new StringBuilder(html);

                sb.Replace("//ajax.lug.ustc.edu.cn/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, , 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;

        }
