ASP.NET (C#) Question

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
.

Answer

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);
