something goes awry. Knowing what they mean enables you to fix the problem, or create custom error pages. The
Http Response
status codes are returned to the client making the request (typically http response example an Internet Browser) and also recorded in the server’s log file. Theses error codes are encoded into
Http Status Code 0
decimal ranges: Error Code Range Type of Error Code Error Code Range Type of Error Code 100 to 199 Informational status codes, rarely used – and generally http code 302 only written to server logs. 200 to 299 Successful, only 200 frequently used – and generally only written to server logs. 300 to 399 Warning – but the request may still be satisfiable. 400 to 499 Client Error, the request was invalid in some way. 500 to 599 Server Error, the server could not http 422 fulfill the (valid) request. 100 Range HTTP Error 100 Continue. Not really an “error”, this HTTP Status Code means everything is working fine. HTTP Error 101 Switching Protocols. Again, not really an “error”, this HTTP Status Code means everything is working fine. 200 Range HTTP Error 200 Success. This HTTP Status Code means everything is working fine. However, if you receive this message on screen, obviously something is not right… Please contact the server’s administrator if this problem persists. Typically, this status code (as well as most other 200 Range codes) will only be written to your server logs. HTTP Error 201 Created. A new resource has been created successfully on the server. HTTP Error 202 Accepted. Request accepted but not completed yet, it will continue asynchronously. HTTP Error 203 Non-Authoritative Information. Request probably completed successfully but can’t tell from original server. HTTP Error 204 No Content. The requested completed successfully but the resource requested is empty (has zero length).

Responses are grouped in five classes: informational responses, successful responses, redirects, client errors, and servers errors. Information responses 100 Continue This interim response indicates that everything so far is OK http status code and that the client should continue with the request or ignore it if it is already finished. 101 Switching Protocol This code is sent in response to an Upgrade: request header by the client, and indicates that the protocol the server is switching too. It was introduced to allow migration to an incompatible protocol version, and is not in common use. Successful responses 200 OK The request has succeeded. The meaning of a success varies depending on the HTTP method: GET: The resource has been fetched and is transmitted in the message body. HEAD: The entity headers are in the message body. POST: The resource describing the result of the action is transmitted in the message body. TRACE: The message body contains the request message as received by the server 201 Created The request has succeeded and a new resource has been created as a result of it. This is typically the response sent after a PUT request. 202 Accepted The request has been received but not yet acted upon. It is non-committal, meaning that there is no way in HTTP to later send an asynchronous response indicating the outcome of p
to provide additional information about request. They indicate how the request was processed, cache effectiveness, use of CDN features and other pertinent information. The codesare added to the log data by the cache engine for every request and to entries in the fill.txt file by the Content Distributor. Two types of extended status codes are produced by the cache engine. “External” codes are those that will appear in customer logs and “internal” codes are used by the CDN. Each digit in the code fields is independently set, and statistics are maintainedfor each. The meanings of each digit are: Digit 1 refers to theleast-significant-digit, etc. Format: D I G I T 14 13 12 11 10 9 8 7 6 5 4 3 2 1 External Extended Status Codes Digit 1 - Hit/Miss This is a simple linear digit, with the following values: 0 - Cache Miss 1 - Cache hit (access to backing store needed) 2 - Cache hit (all from memory) Value 2 is set when the resource was in the in-memory cache and fresh. This can be set on machines with the memory cache disabled if the resource happened to be in memory because of an ongoing previous request for it. 3 - Cache Miss (resource is non-cacheable) Digit 2 - Peer Status This is 4-bit bit field 0000 - Fill/Refresh from the origin server If this digit is 0, then the HTTP request (either for a refresh or load), was made to the origin server. xxx1 - Fill/Refresh from a Peer Bit 1 is set when this machine made the HTTP request to a peer, either sibling or parent. xx1x - Resource served to a Peer Bit 2 is set on the peer (known as the peer-server) which served the resource to its peer (referred to as the peer-client). Normally, there will be a corresponding log entry on the peer-client with bit 1 set. It is possible for this bit to be set because of a diagnostic request that was manually made to this machine. If an 'X-WR-Peer:' request header was added, then the cache will believe it is serving the resource to a peer, and will set bit-2. x1xx - Peer Request forced miss Bit 3, forced miss, is set when the resource being requested is considered to be no long
