Bug 202963 – Wrong HTTP method (POST instead of GET) when reload a page after pushState if previous page was loaded by a POST

• Status: NEW
• Component: History

Created attachment 380942 [details]
a nodejs script to run a local http server on port 8000

To reproduce:

1. use attached nodejs file index.js, run `node index.js`.
2. use Safari to visit http://localhost:8000/
3. click "try" button in the page, it submits a POST form, renders a new page http://localhost:8000/do,
4. now open dev inspector, goto console, run `history.pushState({}, "", "/whatever");`, the browser window now shows latest url "/whatever".
5. use browser window reload button to reload current page.
6. safari should ask you "Are you sure you want to send a form again?", click send.
7. in dev inspector, goto network tab, double check the request to "/whatever", it's a POST request.

This bug was first reported in 2017, so it's likely affecting multiple Safari/webkit versions, not only latest Safari 13.
This wrong behaviour does not affect Chrome and Firefox.
