Every time I've heard this use case come up though it's been in same-origin situations. It could be thus limited. I'm not a huge fan of the idea, but I'm pretty sure that it's make the request go away. >> Redirects should certainly be fixed so as to ignore the "safe methods" >> requirement from HTTP (or HTTP should be fixed to provide better advice). >> Note that the issue is not just prompting, but also switching the method >> from PUT/DELETE to GET. >> >> Why just 307 and not 301-3,8? > > Because only 307/308 preserve the method. Ah, so you meant 307-8. It's not clear to me that (if compatibly possible) the method shouldn't be preserved for 301-3 too, under XHR. Method changing is certainly surprising to developers. Firefox changes POST to GET but not DELETE or PUT for 301-2; it changes all three for 303; none for 307-8. (It also prompts a lot.) Safari changes all of POST, DELETE, and PUT to GET for 301-3 and 308 but not 307. It doesn't prompt. Chrome changes POST to GET but not DELETE or PUT for 301-2; changes all three for 303 and 308; none for 307. It doesn't prompt. I haven't checked IE but I'm pretty sure it has a fourth combination. The only thing that seems consistent is that POST gets changed to GET for 301 and 302; the rest is an unreliable mess. -- Robin Berjon - http://berjon.com/ - @robinberjon
