Check out the Data Compression Proxy for Google Chrome on Desktop (https://chrome.google.com/webstore/detail/ajfiodhbiellfpcjjedhmmmpeeaebmep).
Latest version as of this writing is 1.0, released February 16 2014:
This is an experimental extension for Google Chrome bringing Chrome
Data Compression Proxy from mobile to desktop PCs.
How it works:
The extension sends all HTTP (but not HTTPS) traffic through Chrome
Data Compression Proxy server, which uses SPDY protocol to speed up
web browsing. Enabled state is indicated by a green icon. You can
manually disable the proxy by clicking on the icon. When the proxy
raises an error, it is being automatically disabled for 30 sec, so
that the request can be resent.
The extension uses either chrome.webRequest (slower) in Chrome Stable
or chrome.declarativeWebRequest (faster) in Chrome Beta/Dev, so ignore
