I've noticed that some browsers (Firefox, Opera, IE) cache images without following the HTTP expiry rules. This does not appear to be permitted by the HTML5 specification. I've got a test case for this (with explanation) here: http://ado.is-a-geek.net/expired/tests/image_cache_test.html Boris Zbarsky believes this behaviour is required for compatibility so I think it is worth adding to HTML5. This was discussed on the Mozilla bug tracker here: https://bugzilla.mozilla.org/show_bug.cgi?id=295942 How do other browsers handle this? It seems to be possible to get Opera and IE to throw the image away by changing the src attribute on the img. Are there similar caches for any other type of object or is this just images?
