The requested resource has been moved from this URI to a new location. This redirection is permanent. Clients with link editing capabilities should change the link to the new location.
302 Found:
The requested resource resides temporarily in another location, but it can still be found at the requested URI.
303 See Other:
The response to the requested resource can be found at a different URI, but that response should not be cached by the user agent.
304 Not Modified:

305 Use Proxy:
The requested resource must be accessed by the proxy indicated in the Location: resource.
306:

307 Temporary Redirect:
The resource in question has been moved to a new location, but the user agent should not update the URI to the new location.
