The Intel® Server Board S1200RP UEFI Development Kit supports Pre-Execution Environment (PXE) boot for IPV4 and IPV6 networking using on-board and add-in networking devices. Because of added initialization time, network boot for the four onboard networking devices is disabled by default in firmware setup. Users can enable PXE boot for on-board networking by enabling the ’EFI Network’ setting in the firmware setup menu.

As of SDV.RP.B6, the Intel® Server Board S1200RP UEFI Development Kit supports UEFI HTTP and HTTPS boot. These features are described in whitepapers located on the Tianocore github wiki: https://github.com/tianocore/tianocore.github.io/wiki/EDK%20II%20White%20papers.Well, it could be double-edged sword from security standpoint. It depends on who you ask and what it's being used for.
Anyway, this is my take on this:
- My "educated" guess is: This stuff emerge from Intel collaboration with the so-called Hyperscalers--Hyperscalers is what some people call them (http://www.nextplatform.com/category/hyperscale/). The Hyperscalers (Google, Facebook, Amazon, Azure, Alibaba, Baidu, Tencent) are running lots of web servers. Therefore, it makes sense for them to make it possible for their machines to boot just off of the webservers instead of preparing another "PXE Boot server" due to the prevalent web server in their bit barns. I think that Intel wants to trickle-down the same stuff into the masses, but as the first step, the Enterprise sector is what Intel targets.
- Present day flash (is it still Flash??) memory used for firmware storage is spacious enough to cram a (compressed?) HTTP/HTTPS client into it. It would hardly possible to do that just several years ago due to the space constraint in the firmware chip on the motherboard. I didn't say this is impossible years ago because I have worked with extremely limited firmware space in non-PC platform that somehow managed to cram HTTP server into space less than 1MB, along with hardware configuration software stuff.
- This made it possible to boot from the cloud if anyone wants to implement such a stuff. But, it would entails a huge security "nightmare" if you ask me.
