Initially, SPDY was a proprietary Google protocol implemented only in Google’s Chrome browser. That’s changing, however. Amazon’s Silk browser includes SPDY support, and Firefox 11 will include preliminary SPDY support. Partially motivated by SPDY’s uptake, the IETF’s HTTPbis Working Group — the team of industry experts tasked with maintaining and developing the HTTP specification — is considering
the development of a new specification, HTTP/2.0, with the goal of improving the performance of HTTP connections. The working group will solicit suggestions from the industry, and with two, soon to be three implementations already, SPDY is likely to be well placed among those suggestions.
