why multipart/x-mixed-replace is needed for Comet?
- by Morgan Cheng
I'm reading this article about Comet http://en.wikipedia.org/wiki/Comet_(programming). It mentions that browser should support multipart/x-mixed-replace to make XmlHttpRequest Streaming possible.
Why this multipart/x-mixed-replace is necessary?
Without this header, HTTP response can still be chunked and sent piece by piece to browser, right?
