In Google Chrome, how you can check which files are served from the browser cache, and which comes from the server?
回答1:
In Chrome Developer Tools switch to the Network tab and on the Size column it will either give you the size of the downloaded content or say (from disk/memory cache).
回答2:
If you can't see the size column then you may need to close this window
