A wall girl uses response. Filter to solve the Google CDN problem in stackexchange. Exceptional.

A wall on the ancient road, some open-source Dongdong uses the ancient road CDN, such as predictional and opserver, which leads to slow or unusable services.

Must be replaced

Predictional only needs to replace the page with response. filter, because you have to regularly merge the pages to maintain versions.

Internal class responsestream: memorystream {# region ctor private stream output {Get; set;} public httpcontextbase context {Get; set ;} /// <summary> // stream buffer output on the page /// </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 );}}

The corresponding action is changed:

        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;        }
