Chrome removed support for multipart/x-mixed-replace main resources in this issue:

They made main resources that use multipart/x-mixed-replace trigger downloads instead of being displayed. The observation that multipart/x-mixed-replace support introduces a lot of complexity is absolutely true for us as well. It’s a huge mess. Looks like this patch landed in Chromium on June 13, 2013 and has stuck since then, so removing it has not resulted in a disaster for Chrome. With so few people using multipart/x-mixed-replace, and since now both IE and Chrome do not support it, I suggest that we remove support for it from the docloader as well. - Seth _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
