Are there any significant drawbacks to using a 303 over a 302 redirect? I ask because I've seen this advice a number of times before - typically on StackOverflow - and I've seen a lot of recommendations to use 302. One question I found on a cursory search just now[1] asks whether to use 302 or 303. All three answers submitted to the question recommend 302. The key consideration seems to be backwards compatibility with HTTP 1.0 (the 303 response was apparently added for HTTP 1.1), with the understanding that 302s act close enough to 303s that you don't really need to worry about it. Is this a valid concern, or is this simply an old concern that hasn't died even though the context has changed over the years?
