HTTP-Status: 300-307

300 Multiple Choices

The requested resource (e.g., a URL) could be one of several. The user will be provided with a list of possible choices, or the server could automatically redirect.

301 Moved Permanently

The requested resource has moved to a new URL. A 410 status code is returned if the new address is unavailable or not to be revealed.

302 Found

The requested resource has moved, but the browser is not automatically redirected. Instead the new URL should be presented to the user.

303 See Other

As with 302, the requested resource has moved, but if the request was a GET request, an automatic redirect by the browser is acceptable.

304 Not Modified

If a client has a partial copy of content in its cache and requests and update, but the document has not been modified since cached, the server responds with a 304 status code and does not send the content to the client. This allows updates of local cache information without fewer HTTP requests.

305 Use Proxy

The requested resource (e.g. web page) must be accessed through the URL of the proxy server in this message.

306 (Unused)

Not in use - Reserved

307 Temporary Redirect

As with 302 and 303, this code is for a moved resource. 303 and 307 were created as unambiguous alternatives to 302. 307 is a temporarily moved resource and thus the same URL should be continued to be used.
