XHR multipart response support has been removed

Published: | Categories: DOM | Creative Commons BY-SA 3.0

Description

Support for the multipart property and multipart/x-mixed-replace responses, deprecated since Firefox 20, has been removed from XMLHttpRequest. This was a Firefox-only feature that was never standardized. Server-Sent Events, Web Sockets or inspecting responseText from progress events can be used instead.
