C# - Writing responseStream to context.response.outputstream

Our ASP.net app needs to relay some requests to another server, get the data and serve it. We can download the data to a file and serve it or directly serve the response stream from origin server to client. Data includes js/css/images/font files/mp3 etc.

HttpWebRequest forwardRequest = (HttpWebRequest)WebRequest.Create(remoteUrl);

                forwardRequest.ContentType = context.Request.ContentType;
                forwardRequest.UserAgent = context.Request.UserAgent;
                forwardRequest.Method = context.Request.HttpMethod;

                //add post check

                HttpWebResponse newResponse = (HttpWebResponse)forwardRequest.GetResponse();

                MemoryStream ms = new MemoryStream();
                newResponse.GetResponseStream().CopyTo(ms);

                context.Response.ContentType = newResponse.ContentType;
                context.Response.StatusCode = 200;
                context.Response.BinaryWrite(ms.GetBuffer());
                ms.Close();

                context.Response.Flush();
                context.Response.Close();
                context.Response.End();

How can I directly pass newResponse.GetResponseStream() to context.Response.OutputStream.

You can't pass the stream directly, but you can conveniently write one to the other (which will create a read/write-loop internally):

sourceStream.CopyTo(destinationStream);
