This code indicates that the server has received and is processing the request, but no response is available yet. Wikipedia The client must first authenticate itself with the proxy. 408 Request Timeout The client did not produce a request within the time that the server was prepared to wait. The request MUST have included a Range header field (section 14.35) indicating the desired range, and MAY have included an If-Range header field (section 14.27) to make the request conditional.

The general catch-all error when the server-side throws an exception. 501 Not Implemented The server does not support the functionality required to fulfill the request. Content developers should be aware that there might be clients that implement such a fixed limitation. However, these risks are not unique to the 511 status code; in other words, a captive portal that is not using this status code introduces the same issues.

The client MAY repeat the request with a suitable Authorization header field (section 14.8). The set presented MAY be a subset or superset of the original version. This interim response is used to inform the client that the initial part of the request has been received and has not yet been rejected by the server. This means that the actual status code that is returned depends on how the server software handles a particular error--this guide should generally point you in the right direction Now that you have a high-level understanding of HTTP status codes, we will look at the commonly encountered errors. 400 Bad Request The 400 status code, or Bad Request error, means the HTTP request that was sent to the server has invalid syntax.
Retrieved 16 October 2015. ^ "Mozilla Bugzilla Bug 187996: Strange behavior on 305 redirect". The applications may choose to learn, or not. The 511 status code is designed to mitigate problems caused by "captive portals" to software (especially non-browser agents) that is expecting a response from the server that a request was made to, not the intervening network infrastructure. Http 422 User agents SHOULD display any included entity to the user.
Note: RFC 1945 and RFC 2068 specify that the client is not allowed to change the method on the redirected request. Http Status Codes Cheat Sheet Since HTTP/1.0 did not define any 1xx status codes, servers must not[note 1] send a 1xx response to an HTTP/1.0 client except under experimental conditions. 100 Continue The server has received the request headers and the client should proceed to send the request body (in the case of a request for which a body needs to be sent; for example, a POST request). The client MAY repeat the request if it adds a valid Content-Length header field containing the length of the message-body in the request message. 10.4.13 412 Precondition Failed The precondition given in one or more of the request-header fields evaluated to false when it was tested on the server. https://msdn.microsoft.com/en-us/library/dd891284.aspx Used when the requested resource is not found, whether it doesn't exist or if there was a 401 or 403 that, for security reasons, the service wants to mask. 405 Method Not Allowed The method specified in the Request-Line is not allowed for the resource identified by the Request-URI.
The new URI is not a substitute reference for the originally requested resource. Http Code 302 If so, the headers of the resulting instance are the result of combining the headers from the status-226 response and the other instances, following the rules in section 13.5.3 of the HTTP/1.1 specification. Important: The client should compare existing device settings against policy updates to ensure that it is compliant with the updated policy. Unless otherwise stated, the status code is part of the HTTP/1.1 standard (RFC 7231). The Internet Assigned Numbers Authority (IANA) maintains the official registry of HTTP status codes. Microsoft IIS sometimes uses additional decimal sub-codes to provide more specific information, but not all of those are here (note that these sub-codes only appear in the response payload and in documentation; not in the place of an actual HTTP status code).
If possible, the server should use the Range header to indicate what time period it may still be able to record. http://100pulse.com/http-statuscode/449.jsp Retrieved 16 October 2015. ^ "RFC 7231, Section 6.3.4.". ^ "RFC 7230, Section 5.7.2.". ^ Simmance, Chris. "Server Response Codes And What They Mean". Http Status Code 400 The 303 response MUST NOT be cached, but the response to the second (redirected) request might be cacheable. Http Response Example However, this specification does not define any standard for such automatic selection.

Http Code 403
Originally meant "Subsequent requests should use the specified proxy." 307 Temporary Redirect The requested resource resides temporarily under a different URI. Upon receiving a 410 status code, the client should not request the resource again in the future. The request might or might not eventually be acted upon, as it might be disallowed when processing actually takes place. 203 Non-Authoritative Information (since HTTP/1.1) The server successfully processed the request, but is returning information that may be from another source. 204 No Content The server successfully processed the request, but is not returning any content. 205 Reset Content The server successfully processed the request, but is not returning any content. check over here Click on the category heading or the status code link to read more. 1xx Informational This class of status code indicates a provisional response, consisting only of the Status-Line and optional headers, and is terminated by an empty line.
In this case, the response entity would likely contain a list of the differences between the two versions in a format defined by the response Content-Type. 10.4.11 410 Gone The requested resource is no longer available at the server and no forwarding address is known. Http 504 The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address. The 304 response MUST NOT contain a message-body, and thus is always terminated by the first empty line after the header fields.
Wikipedia Indicates that the resource requested is no longer available and will not be available again. The new permanent URI SHOULD be given by the Location field in the response.

These response codes are applicable to any request method. 10.5.1 500 Internal Server Error The server encountered an unexpected condition which prevented it from fulfilling the request. 10.5.2 501 Not Implemented The server does not support the functionality required to fulfill the request.
If the existing password does not conform to these updated policy settings or if the client cannot verify that the current password meets the requirements, the client should prompt the user to configure a new password. See section 8.2.3 for detailed discussion of the use and handling of this status code. 10.1.2 101 Switching Protocols The server understands and is willing to comply with the client's request, via the Upgrade message header field (section 14.42), for a change in the application protocol being used on this connection. Wikipedia The URI provided was too long for the server to process. 415 Unsupported Media Type The server is refusing to service the request because the entity of the request is in a format not supported by the requested resource for the requested method. The actual response will depend on the request method used.
File Permissions 403 errors commonly occur when the user that is running the web server process does not have sufficient permissions to read the file that is being accessed. Text is available under the Creative Commons Attribution-ShareAlike License; additional terms may apply. This class of status code indicates a provisional response, consisting only of the Status-Line and optional headers, and is terminated by an empty line. This response MUST NOT use the multipart/byteranges content- type. 10.4.18 417 Expectation Failed The expectation given in an Expect request-header field (see section 14.20) could not be met by this server, or, if the server is a proxy, the server has unambiguous evidence that the request could not be met by the next-hop server. 10.5 Server Error 5xx Response status codes beginning with the digit "5" indicate cases in which the server is aware that it has erred or is incapable of performing the request.
Unless it was a HEAD request, the response SHOULD include an entity containing a list of resource characteristics and location(s) from which the user or user agent can choose the one most appropriate. This rare condition is only likely to occur when a client has improperly converted a POST request to a GET request with long query information, when the client has descended into a URI "black hole" of redirection (e.g., a redirected URI prefix that points to a suffix of itself), or when the server is under attack by a client attempting to exploit security holes present in some servers using fixed-length buffers for reading or manipulating the Request-URI. 10.4.16 415 Unsupported Media Type The server is refusing to service the request because the entity of the request is in a format not supported by the requested resource for the requested method. 10.4.17 416 Requested Range Not Satisfiable A server SHOULD return a response with this status code if a request included a Range request-header field (section 14.35), and none of the range-specifier values in this field overlap the current extent of the selected resource, and the request did not include an If-Range request-header field. (For byte-ranges, this means that the first- byte-pos of all of the byte-range-spec values were greater than the current length of the selected resource.) When this status code is returned for a byte-range request, the response SHOULD include a Content-Range entity-header field specifying the current length of the selected resource (see section 14.16). Since the redirection might be altered on occasion, the client SHOULD continue to use the Request-URI for future requests. Error code response for missing or invalid authentication token. 402 Payment Required This code is reserved for future use.
If the 401 response contains the same challenge as the prior response, and the user agent has already attempted authentication at least once, then the user SHOULD be presented the entity that was given in the response, since that entity might include relevant diagnostic information. For instance, a POST request must be repeated using another POST request. 308 Permanent Redirect (experiemental) Wikipedia The request, and all future requests should be repeated using another URI. 307 and 308 (as proposed) parallel the behaviours of 302 and 301, but do not require the HTTP method to change. When sending a 449 status code, the server MUST include the Ms-Echo-Request header.
