Where is non-GET/POST stored

[annevk]

Another question for @smaug---- and @majido. The HTML Standard hints at some point that history session entries store whether the URL was retrieved using GET or POST.

This information is also used when a document is reloaded (a prompt shows up to ask the user if they're sure they want to submit the data again). Would we then get it from the session history's current entry or is it also stored elsewhere?

"also stored"? Is there a thing stored elsewhere?

Anyhow, Gecko stores the post data in session history entry

and that is used when reloading

Necko then uses "POST" method if such post data is used.

I was just curious if I missed something. I suspect this can probably all live on the session history entry as "form data" (as it's called now). That's probably good enough although maybe not as there's also the correct Content-Type header to set, Referer might have to be reused, etc.
