HTTPBoot was added into UEFI SPEC since 2.5. It aims to replace PXE and provides more features. Actually, the concept of HTTPBoot is similar to PXE. It starts with the HTTP URL from the DHCP server and fetches the data with the HTTP protocol. The key difference between HTTPBoot and PXE is the support of DNS. With DNS, the firmware and the bootloader can resolve the domain name so it's possible to pass the well-known URL to download the image instead of the explicit IP URL. Besides, HTTP is designed to cross different domains, while tftp (PXE) is only for the local network.
