Your solution then is obviously to prevent forcing of just the text/html parts. Is *seems* the right thing to do - but isn't. In doing that you overlook the fact that the text/html part is what makes the other non-HTML parts so "dynamic". Every single page load of the text/html part may be pointing to different scripts, images, videos etc causing the ones already in your cache to be ignored and the new ones fetched. This is a drag on your cache now having to track N copies of what the page *used* to look like, but those images/videos/etc may never again be used. What we call the "cache control" headers (date, cache-control, expires, last-modified, etag etc) are not what makes the content dynamic, they are just indications by the site author / server of how long the HTML parts of the site are going to be making use of those objects. The dynamic bit is usually the HTML and how it references things. Store-ID gets around that a little bit by telling your cache that *you think* certain objects are going to be used under multiple names with some pattern regex can match _reliably_. The *right* thing to be doing is to let sites determine their own caching and only use the forced caching for specific sites (and if possible specific URLs) which are found to be broken.
