| Those nasty ....ERROR CODES
and what they all mean Sometimes when you try to visit a
Web site, instead of seeing what you expected, you see an error code. Some of these codes
may be all to familiar to you, but there are a lot that you may have never seen or have
and would like to know what they mean. To give you a greater understanding of these
errors, here is a list of the most popular error codes.
As a rule of thumb, the first thing you should do if you get an
error, is make sure that you have typed in the URL or page address correctly. Also try
refreshing your page request, sometimes its a simple case of "net conjestion".
Error codes 401- 408
Bad request 400
The request could not be understood by the server due to bad syntax. You should not repeat
the request without modifications.
Unauthorized 401
The creators of a Web page may want only certain people have access to that page. You
should only retry the request if you know that you have authorization.
PaymentRequired 402
This message gives a specification of charging schemes which are acceptable. You may retry
the request with a suitable ChargeTo header.
Forbidden 403
The request is for something forbidden. Authorization will not help. This status code is
commonly used when the server does not wish to reveal exactly why the request has been
refused, or when no other response is applicable. (The file needs to be set with
"read permissions" for all users.)
Not found 404
The server has not found anything matching what you requested. Make sure that the Web
address (URL) that you typed in exactly matches the address you were given. Check that the
capitalization matches, spelling, and punctuation, like dots (.) and slashes (/),
are correctly placed. Be sure you are using the forward slash (/) and not the
backward slash (\).
405 Method Not Allowed
The method specified in the Request-Line is not allowed for the resource identified by the
request. The response must include an Allow header containing a list of valid methods for
the requested resource.
406 Not Acceptable
The resource identified by the request is only capable of generating response entities
which have content characteristics not acceptable according to the accept headers sent in
the request.
407 Proxy Authentication Required
This code is similar to 401 (Unauthorized), but indicates that you must first authenticate
yourself with the proxy. The proxy must return a Proxy-Authenticate header field (section
14.33) containing a challenge applicable to the proxy for the requested resource. You may
repeat the request with a suitable Proxy-Authorization header field (section 14.34). HTTP
access authentication is explained in section 11.
408 Request Timeout
The client did not produce a request within the time that the server was prepared to wait.
You may repeat the request without modifications at any later time.
