Difference between HTTP redirect codes

by
  • 301: Permanent redirect. Clients making subsequent requests for this resource should use the new URI. Clients should not follow the redirect automatically for POST/PUT/DELETE requests.
  • 302: Redirect for undefined reason. Clients making subsequent requests for this resource should not use the new URI. Clients should not follow the redirect automatically for POST/PUT/DELETE requests.
  • 303: Redirect for undefined reason. Typically, ‘Operation has completed, continue elsewhere.’ Clients making subsequent requests for this resource should not use the new URI. Clients should follow the redirect for POST/PUT/DELETE requests, but use GET for the follow-up request.
  • 307: Temporary redirect. Resource may return to this location at a later point. Clients making subsequent requests for this resource should use the old URI. Clients should not follow the redirect automatically for POST/PUT/DELETE requests.

I personally recommend avoiding 302 if you have the choice. Many clients do not follow the spec when they encounter a 302. For temporary redirects, you should use either 303 or 307, depending on what type of behavior you want on non-GET requests. Prefer 307 to 303 unless you need the alternate behavior on POST/PUT/DELETE.
