More About Data Compression Proxy

This is an experimental extension for Google Chrome bringing Chrome Data Compression Proxy from mobile to desktop PCs. It is a huge data saver!

Now with statistics, ad blocking and a bypass list, which you can customize in options.

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 adjustable number of seconds, so that the request can be resent.

The extension uses either chrome.webRequest (slower) in Chrome Stable or chrome.declarativeWebRequest (faster but without stats) in Chrome Beta/Dev.


Please ignore the following warning, the extension works fine anyway:
"This extension failed to modify the request header "Chrome-Proxy" of a network request because the modification conflicted with another extension (Data Compression Proxy)."

The extension works as long as you see the following response header:
"via: 1.1 Chrome Compression Proxy"
