There are multiple options for the requested resource. For example, this code could be used to present a list of resource characteristics and addresses from which the client such as a browser may choose. |
301 |
Moved Permanently |
This and all future requests have been permanently moved to the given URI indicated in this response. |
302 |
Found |
The requested resource was temporarily moved. |
303 |
See Other |
The response to the request can be found under another URI using a GET or POST method. |
304 |
Not Modified |
The requested resource has not been modified. When the server returns this status code, it does not return any resources. |
305 |
Use Proxy |
The requested resource is available only through a proxy. |
306 |
Unused |

401 |
Unauthorized |
The authorization information provided by the client is incorrect or invalid. |
402 |
Payment Required |
Reserved for future use. |
403 |
Forbidden |
The server has received the request and understood it, but the server is refusing to respond to it. The client should modify the request instead of re-initiating it. |
404 |
NotFound |
The requested resource cannot be found. The client should modify the request instead of re-initiating it. |
405 |
MethodNotAllowed |
A request method is not supported for the requested resource. The client should modify the request instead of re-initiating it. |
406 |
Not Acceptable |
The server cannot fulfill the request based on the content characteristics of the request. |
407 |
Proxy Authentication Required |
This code is similar to 401, but indicates that the client must first authenticate itself with the proxy. |
