The indicating in the achievement is dependent on the HTTP system: • • GET: The resource has long been fetched and is particularly despatched while in the concept system. SetorArticle: The resource describing the consequence on the action is transmitted in the message human body.

It was Utilized in a previous version of the HTTP/one.1 specification.307 Temporary RedirectThe host sends this response to manual the shopper to get the requested resource at another URI with similar treatment that was utilised in the prior petition. This has the very same semantics since the302 DiscoveredHTTP response code, with the exception the user consultant have to not adjust the HTTP technique employed: If aPOSTwas utilized at the 1st petition, aWrite-uphave to be utilized at the upcoming request.308 Permanent RedirectThis implies that the source is now permanently Found at Yet another URI, specified from thePlace:HTTP Response header.

From the browser, this commonly suggests the URL isn't really recognized. In an API, this can also show the endpoint is legitimate nevertheless the useful resource alone will not exist.
