'description': '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). Sending a large request body to a server after a request has been rejected for inappropriate headers would be inefficient. To have a server check the request\'s headers, a client must send Expect: 100-continue as a header in its initial request and receive a 100 Continue status code in response before sending the body. If the client receives an error code such as 403 (Forbidden) or 405 (Method Not Allowed) then it shouldn\'t send the request\'s body. The response 417 Expectation Failed indicates that the request should be repeated without the Expect header as it indicates that the server doesn\'t support expectations (this is the case, for example, of HTTP/1.0 servers).',
'standard' : 'http'
},

'description': 'The requester has asked the server to switch protocols and the server has agreed to do so.',
'standard' : 'http'
},
102: { 'name' : 'Processing (WebDAV; RFC 2518)',
'description': 'A WebDAV request may contain many sub-requests involving file operations, requiring a long time to complete the request. This code indicates that the server has received and is processing the request, but no response is available yet. This prevents the client from timing out and assuming the request was lost.',
'standard' : 'http'
},
200: { 'name' : 'OK',
'description': 'Standard response for successful HTTP requests. The actual response will depend on the request method used. In a GET request, the response will contain an entity corresponding to the requested resource. In a POST request, the response will contain an entity describing or containing the result of the action.',
'standard' : 'http'
},

'description': 'The request has been fulfilled, resulting in the creation of a new resource.',
'standard' : 'http'
},
202: { 'name' : 'Accepted',
'description': 'The request has been accepted for processing, but the processing has not been completed. The request might or might not be eventually acted upon, and may be disallowed when processing occurs.',
'standard' : 'http'
},
203: { 'name' : 'Non-Authoritative Information (since HTTP/1.1)',
'description': 'The server is a transforming proxy (e.g. a Web accelerator) that received a 200 OK from its origin, but is returning a modified version of the origin\'s response.',
'standard' : 'http'
},

'description': 'The server successfully processed the request and is not returning any content.',
'standard' : 'http'

205: { 'name' : 'Reset Content',
'description': 'The server successfully processed the request, but is not returning any content. Unlike a 204 response, this response requires that the requester reset the document view.',
'standard' : 'http'
},
206: { 'name' : 'Partial Content (RFC 7233)',
'description': 'The server is delivering only part of the resource (byte serving) due to a range header sent by the client. The range header is used by HTTP clients to enable resuming of interrupted downloads, or split a download into multiple simultaneous streams.',
'standard' : 'http'
},

},
300: { 'name' : 'Multiple Choices',
'description': 'Indicates multiple options for the resource from which the client may choose (via agent-driven content negotiation).

'description': 'This and all future requests should be directed to the given URI.',
'standard' : 'http'
},
302: { 'name' : 'Found',
'description': 'This is an example of industry practice contradicting the standard. The HTTP/1.0 specification (RFC 1945) required the client to perform a temporary redirect (the original describing phrase was "Moved Temporarily"), but popular browsers implemented 302 with the functionality of a 303 See Other. Therefore, HTTP/1.1 added status codes 303 and 307 to distinguish between the two behaviours. However, some Web applications and frameworks use the 302 status code as if it were the 303.',

},
303: { 'name' : 'See Other (since HTTP/1.1)',
'description': 'The response to the request can be found under another URI using the GET method. When received in response to a POST (or PUT/DELETE), the client should presume that the server has received the data and should issue a new GET request to the given URI.',

'description': 'Indicates that the resource has not been modified since the version specified by the request headers If-Modified-Since or If-None-Match. In such case, there is no need to retransmit the resource since the client still has a previously-downloaded copy.',
'standard' : 'http'
},
305: { 'name' : 'Use Proxy (since HTTP/1.1)',
'description': 'The requested resource is available only through a proxy, the address for which is provided in the response. Many HTTP clients (such as Mozilla and Internet Explorer) do not correctly handle responses with this status code, primarily for security reasons.',

'description': 'No longer used. Originally meant "Subsequent requests should use the specified proxy."',
'standard' : 'http'
},
307: { 'name' : 'Temporary Redirect (since HTTP/1.1)',
'description': 'In this case, the request should be repeated with another URI; however, future requests should still use the original URI. In contrast to how 302 was historically implemented, the request method is not allowed to be changed when reissuing the original request. For example, a POST request should be repeated using another POST request.',
'standard' : 'http'
},
308: { 'name' : 'Permanent Redirect (RFC 7538)',
'description': 'The request and all future requests should be repeated using another URI. 307 and 308 parallel the behaviors of 302 and 301, but do not allow the HTTP method to change. So, for example, submitting a form to a permanently redirected resource may continue smoothly.',

'description': 'Similar to 403 Forbidden, but specifically for use when authentication is required and has failed or has not yet been provided. The response must include a WWW-Authenticate header field containing a challenge applicable to the requested resource. See Basic access authentication and Digest access authentication. 401 semantically means "unauthenticated", i.e. the user does not have the necessary credentials.',
'standard' : 'http'
},
402: { 'name' : 'Payment Required',
'description': 'Reserved for future use. The original intention was that this code might be used as part of some form of digital cash or micropayment scheme, as proposed for example by GNU Taler, but that has not yet happened, and this code is not usually used. Google Developers API uses this status if a particular developer has exceeded the daily limit on requests. Stripe API uses this code for errors with processing credit cards.',
'standard' : 'http'
},

'description': 'Indicates that the request could not be processed because of conflict in the request, such as an edit conflict between multiple simultaneous updates.',
'standard' : 'http'
},
410: { 'name' : 'Gone',
'description': 'Indicates that the resource requested is no longer available and will not be available again. This should be used when a resource has been intentionally removed and the resource should be purged. Upon receiving a 410 status code, the client should not request the resource in the future. Clients such as search engines should remove the resource from their indices. Most use cases do not require clients and search engines to purge the resource, and a "404 Not Found" may be used instead.',

411: { 'name' : 'Length Required',
'description': 'The request did not specify the length of its content, which is required by the requested resource.',

'description': 'The client has asked for a portion of the file (byte serving), but the server cannot supply that portion. For example, if the client asked for a part of the file that lies beyond the end of the file. Called "Requested Range Not Satisfiable" previously.',

'description': 'This code was defined in 1998 as one of the traditional IETF April Fools\' jokes, in RFC 2324, Hyper Text Coffee Pot Control Protocol, and is not expected to be implemented by actual HTTP servers. The RFC specifies this code should be returned by teapots requested to brew coffee. This HTTP status is used as an Easter egg in some websites, including Google.com.',

'standard' : 'http'
},
501: { 'name' : 'Not Implemented',
'description': 'The server either does not recognize the request method, or it lacks the ability to fulfill the request. Usually this implies future availability (e.g., a new feature of a web-service API).',
