High Quality Content by WIKIPEDIA articles! SPDY (pronounced speedy) is a networking protocol for transporting web content developed by Google and used in accessing Google web services from their browser Google Chrome. Google promotes the protocol in the open-source project Chromium to augment the Hypertext Transfer Protocol (HTTP) protocol, achieving higher transmission speed through compression, which is one of the project`s key goals. The name is not an acronym, but is a shortened version of the word SPeeDY, which is essentially the form that is used in its putative logo. However, SPDY™ is a trademark of Google.
