HTTP is updating to HTTP/2! According to this article in Gizmodo, benefits include:
It should make for faster page loads, ensure connections last longer and facilitate servers to push data to your cache, so your computer doesn't have to pull it at a later date.
It should also overcome one headache that developers have long bemoaned. Currently, multiple HTTP requests bog servers down, actually preventing pages loads in the process; the new standard will allow multiplexing, so that multiple requests can be delivered on simultaneously. It will also play nicely with APIs, offer more scope for better encryption, and plenty more to boot.
