How data compression proxy works
The proxy server receives the request initiated on the mobile device, initiates a request for the required resource on your behalf, and then optimizes each response before delivering it back to the client. The content optimization is performed by our open-source PageSpeed libraries, which are specifically tuned for the Chrome Mobile browser. The rendering of the page, and all JavaScript execution, is performed by the client’s browser.
•Secure connections (HTTPS) are routed directly from your mobile device to the destination, bypassing the compression proxy.
•The use of the compression proxy does not require a Google account.
•Navigation in incognito tabs bypasses the compression proxy.
Curious to see the bandwidth savings provided by the proxy? Visit your browser settings to see a graph of the original data size vs. the optimized version that your browser received. The bandwidth savings add up quickly!
