Sometimes when you go to a web site, instead of seeing what the web page supposed to be, you see an error code on that page. You may be familiar with some of these error codes, but there are a lot that you may have never seen. As a web page designer, it is important to understand these error code. We usually group the error code as follows:
100-199: Information codes which are rarely used. They are generally only written to server logs.
200-299: Indicate that the request was accepted or the requested file has no content. Only 200 frequently used.
300-399: Redirects. Requested content has moved or the request may still be satisfiable.
400-499: Client errors indicating the request was invalid in some way.
500-599: Server errors indicating a problem at the server end and the server could not fulfil the valid request.
The following are some common error code.
Error code 400: Bad request usually due to the bad systax which the server could not understand.
Error code 401: Unauthorized access to that page.
Error code 402: Payment Required Error.
Error code 403: You do not have the permission to visit that page and are blocked by that domain.
Error code 404: The page you were trying to look at was not found on the server.
Error code 405: Method not allowed. 405 errors often arise with the POST method.
Error code 406: The format of the page is not acceptable.
Error code 407: This code is similar to error code 401, but it indicates that the client must first authenticate itself with the proxy.
Error code 408: Request timeout, that is, the client failed to produce a request within the time that the server was supposed to wait.
Error code 409: The request could not be completed due to a conflict with the current state of the resource.
Error code 410: Indicates that the resource requested is no longer available and will not be available again.
Error code 411: The request did not specify the length of its content, which is required by the requested resource.
Error code 412: Precondition failed, that is, the server does not meet one of the preconditions that the requester put on the request.
Error code 413: The request is larger than the server is willing or able to process.
Error code 414: The server refuses to take the request because the Request-URI is longer than the server is willing to interpret.
Error code 415: Unsupported media type.
Error code 500: Internal server error. This is a generic error message which is given when no more specific message is suitable. It is usually caused by a CGI error.
Error code 501: Not implemented. The server either does not recognize the request method, or it is not capable of supporting it for any resource.
Error code 502: Bad Gateway. The server was acting as a gateway or proxy and received an invalid response from the upstream server.
Error code 503: Service Unavailable. The server is currently unavailable because it is overloaded or down for maintenance.
Error code 504: Gateway Timeout. The server as a gateway or proxy did not receive a timely response from the upstream server.
