Both frames render identically — that's the goal. The win is in the bytes and requests
below, not the look. They're served live by the mod_pagespeed module on
demo-httpd-1.1.modpagespeed.com; the optimized frame
applies only this filter. Right after a cache purge it may briefly match the original while
the worker rewrites it — reload to see the result.

This is one of 49 filters the mod_pagespeed module applies in place — self-hosted on Apache, nginx, and IIS. Install and run it: it optimizes right away and adds the optimized response headers shown above. Open source under the Apache License 2.0 — free in development and in production.
