The formal process of speeding up Hypertext Transfer Protocol is under way with proposals from Google, Microsoft, and others. There are differences -- but common ground, too.

At a meeting of the Internet Engineering Task Force (IETF) here yesterday, the working group overseeing HTTP formally opened a dicussion about how to make the technology faster. That discussion included presentations about four specific proposals for HTTP 2.0, including SPDY, developed at Google and already used in the real world, and HTTP Speed+Mobility, developed at Microsoft and revealed Wednesday.
