Firefox does not respect max-age for a url with version number based querystring

Posted

Both IE & Chrome respect max-age even with querystring in the url. They have the right behavior.

But in FF (18.0.2 & earlier as well) still pulls the resource from the server even if its within max-age and the querystring in the url was already requested earlier.

Application

  • User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1312.57 Safari/537.17

Firefox may have some unique rules on when pages are cached or not cached. Does this article suggest any reason why the page might not be cached? https://developer.mozilla.org/En/Using_Firefox_1.5_caching

Someone mentioned that if FF gets a querystring it always goes for a unconditional request (even if the querystring was already requested earlier) http://webmasters.stackexchange.com/questions/16011/why-doesnt-firefox-cache-my-images-and-css
