Comment on Suggestion to decrease server bandwidth load

Firefox webdev console request headers (minus my personal cookie), where I’m already on the page and just click the refresh button. No if-modified-since sent to the server to trigger a proper 304 response:

It could be that Firefox doesn’t cache files if the URL has a query parameter.

  Sadly, no - I run an extension called “Don’t accept webp” causing that, I disabled it as soon as I saw the param to test and there’s no difference with or without the param. (webdev console request headers)
