Request successful (followed by response documents to GET and POST requests.)
201 Created
The request is created and new resources are created.
202 Accepted
The request for processing has been accepted, but processing is not completed.
203 Non-authoritative Information
The document has been returned normally, but some response headers may be incorrect because a copy of the document is used.
204 No Content
No new documents. The browser should continue to display the original document. This status code is useful if the user refreshes the page regularly and the servlet can determine that the user's document is current enough.
205 Reset Content

The server tells the client that the original buffered document can continue to be used.
305 Use Proxy
Documents requested by the client should be retrieved through the proxy server specified by the Location header.
