Shift-Reload should mark the request as not drawing from cache. But the response I see doesn't have any validity information. That might mean that you might be getting heuristic caching. That said, after testing this on [1], the time spent waiting (almost 3s) seems to indicate that no cache is involved. A simple reload was enough to induce that delay, not the cache-busting shift-reload. In this case, that means setting Cache-Control: max-age=0 on the request, which seems to be enough.

Hi Michael - Sorry if I'm missing a detail, but I'm not sure whether you're using the IETF rfcdiff (www.ietf.org/rfcdiff) or whether you're using Henrik's Tools servers (tools.ietf.org/rfcdiff) . I can of course only speak for the former. If you're on www.ietf.org, I have reviewed the Cloudflare configuration, and I can tell you that: www.ietf.org/rfcdiff/* www.ietf.org/tools/* are both *NOT* cached. That is to say Cloudflare is configured to always pass those things through to our server without caching or storage. > Shift-Reload should mark the request as not drawing from cache.

And, of course, the *sources* of your txt files might be cached on their end - I have no idea, for example, what github might be doing...
