HTTP_STATUS_REDIRECT_METHOD

A common use is the POST/redirect/GET pattern: after accepting form data, the server returns 303 and a Location header for a resource that describes the result.

The redirect target is not a substitute for the original request body. Clients normally follow 303 with GET or HEAD, avoiding an accidental repeat of the submitted operation.

RFC 9110: HTTP Semantics

Operational meaning of HTTP 303 for HTTP_STATUS_REDIRECT_METHOD

HTTP 303 (HTTP_STATUS_REDIRECT_METHOD) is a redirection response. AllStat records its meaning as “303 See Other”. For HTTP_STATUS_REDIRECT_METHOD, interpret it with the request method, selected representation, response headers, and the specification or product that defines the code; the number alone does not prove that application work completed.

  • Apply the method-rewrite and caching rules defined for HTTP_STATUS_REDIRECT_METHOD, not a generic redirect rule.
  • For HTTP_STATUS_REDIRECT_METHOD, validate the Location target and prevent redirect loops across proxies or canonicalization layers.
