Introduction HTTP defines a set of status codes for the purpose of redirecting a request to a different URI ([RFC3986]). The history of these status codes is summarized in Section 6.4 of [RFC7231], which also classifies the existing status codes into four categories. The first of these categories contains the status codes 301 (Moved Permanently), 302 (Found), and 307 (Temporary Redirect), which can be classified as below: +-------------------------------------------+-----------+-----------+ | | Permanent | Temporary | +-------------------------------------------+-----------+-----------+ | Allows changing the request method from | 301 | 302 | | POST to GET | | | | Does not allow changing the request | - | 307 | | method from POST to GET | | | +-------------------------------------------+-----------+-----------+ Section 6.4.7 of [RFC7231] states that it does not define a permanent variant of status code 307; this specification adds the status code 308, defining this missing variant (Section 3). This specification contains no technical changes from the Experimental RFC 7238, which it obsoletes. 2. Notational Conventions The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. Reschke Standards Track [Page 2] RFC 7538 HTTP Status Code 308 April 2015 3. 308 Permanent Redirect The 308 (Permanent Redirect) status code indicates that the target resource has been assigned a new permanent URI and any future references to this resource ought to use one of the enclosed URIs.Show full document text
