You'd need to introduce something new for that. Many servers compute ETags today as hashes of inputs to a process.
(Which is nice computationally, since you can immediately say "not modified" instead of building the response, hashing it, and throwing it away if the hash matches)
- debugnik 4y agoWell, I said "just hashes" for sort, but such ETag formats could agree on other algorithms as well, as long as the browser can verify them. And introducing a new method doesn't solve the issue of deprecating the existing abusable methods, which is why I suggested one that can already be implemented by privacy-first browsers one-sidedly. Servers would then be pressured to migrate to some friendly ETag format if they don't want to completely lose client-side caching for a (hopefully growing) share of their userbase.
