SPDY

Summary

• SPDY is a transport protocol designed as a successor to HTTP as part of Google's "Let's make the web faster" initiative.
• The SPDY implementation wraps the existing HTTP implementation as a sort of in-browser proxy. This preserves all of the existing HTTP semantics and tools (e.g. firebug), while leveraging the on-the-wire benefits of SPDY.
• This feature is targeted for Firefox 13, but has also landed in Firefox 11.0 and 12.0 as preffed off.

Use Cases

• When SPDY is enabled, all the Google services are using it without any issues.
• When SPDY is disabled, the Google services work fine without using SPDY at all.
• HTTP/1.x based SSL pages work fine both when SPDY is enabled and when it is disabled.
