This is not the case. Every single TCP RST you send on an active http connection will lead to an http request failing in a way which causes application brokenness. No browser auto-retries in that case. The user always has to hit refresh to fix it.

At least with the TCP RST it'll fail fast. What's annoying is that some providers decide that you aren't worthy of the RST; then your browser has to wait for like 3 minutes until the timeout is reached — really annoying.
