That is probably true, since x-mixed-replace started the whole chunked transfer encoding.
It’s probably also what really triggered the invention of comet and later xhr. Netscape was way ahead and Microsoft just pushed it out with money, integration, activex? and of course unfair advantage.
Frames were the common way to deal with that, but I even did stuff with having a separate "named" browser window.
