301 redirect vs. 303 redirect
When would you use 303 redirect? I often use 301, sometimes 302, but I have never used 303. What's the use case for it?
You don't really need the 303 redirect.
303 - See other (from RFC 7231)
The 303 (See Other) status code indicates that the server is redirecting the user agent to a different resource, as indicated by a URI in the Location header field, which is intended to provide an indirect response to the original request. A user agent can perform a retrieval request targeting that URI (a GET or HEAD request if using HTTP), which might also be redirected, and present the eventual result as an answer to the original request. Note that the new URI in the Location header field is not considered equivalent to the effective request URI.
