Editing MIME (section)

====x-mixed-replace====
The content type multipart/x-mixed-replace was developed as part of a technology to emulate [[Push technology|server push]] and streaming over HTTP.

All parts of a mixed-replace message have the same semantic meaning. However, each part invalidates{{snd}} "replaces"{{snd}} the previous parts as soon as it is received completely. Clients should process the individual parts as soon as they arrive and should not wait for the whole message to finish.
