I need a chrome or Firefox add on (or other method) to determine when the content I am viewing is loaded from Local browser cache or from the web server. Preferably breaking down each item as an image may be cached while other content on the same page may be from the server depending on expiry times and other headers.

  • You can get all this information from Firebug or Chrome's developer tools. –  Jan 27 '14 at 00:35
  • I am sure you're right, but where do I look exactly is my question (dev tools has a lot of functionality). – GL2014 Jan 27 '14 at 00:40

    this is possible using a Chrome extension and the remote.debugging api. You would capture the network requests using this which give you timing, headers, cache details and the actual content itself. These are some of the details you can capture: https://developers.google.com/chrome-developer-tools/docs/protocol/1.1/network and there are absolutely loads more – Geezer68 Jan 27 '14 at 00:40

As Geezer68 mentioned, you can use the Chrome Developer tools. Specifically, use the Javascript Console's Network tab and view the Size field which will specify (from cache) when the browser cache returns the content requested.
