All browsers (and all libraries) that I know of, upon receiving a 302 Found in response to a POST will treat it as a 303 See Other and make a simple GET request to the Location, rather than redirecting the POST as the spec requires. Response codes 307 and 308 are proposed as a way to emphatically retain the verb and contents as 301 and 302 are inconsistently applied.
Is there any browser or library, preferably a major browser, that has the specified, uncommon behaviour?
