Status Code

When a client makes a request, one item the server sends back is a status code,
which is a three-digit numeric code. There are four categories of status codes:
• Status codes in the 100–199 range indicate a provisional response.
• Status codes in the 200–299 range indicate a successful transaction.
• Status codes in the 300–399 range are returned when the URL can't be retrieved
because the requested document has moved.
• Status codes in the 400–499 range indicate an error in the request (document
doesn't exist, authorization is required, and so on).
• Status codes of 500 and higher indicate that the server can't perform the
request, or an error has occurred.
Table B-2 contains some common status codes.

Common HTTP status codes
Meaning
OK; successful transmission. This is not an error.
Found. Redirection to a new URL. The original URL has
moved. This is not an error; most browsers will get the new
page.
Use a local copy. If a browser already has a page in its
cache, and the page is requested again, some browsers
(such as Netscape) relay to the web server the
"last-modified" timestamp on the browser's cached copy.
If the copy on the server is not newer than the browser's
copy, the server returns a 304 code instead of returning the
page, reducing unnecessary network traffic. This is not an
error.
Unauthorized. The user requested a document but didn't
provide a valid username or password.
Forbidden. Access to this URL is forbidden.
Not found. The document requested isn't on the server.
This code can also be sent if the server has been told to
protect the document by telling unauthorized people that it
doesn't exist.
