includes codes from IETF internet standards, other IETF RFCs, other specifications, and some additional commonly http code 403 used codes. The first digit of the status code specifies one of five classes of response; an HTTP client must recognise these
Http Code 302
five classes at a minimum. The phrases used are the standard wordings, but any human-readable alternative can be provided. Unless otherwise stated, the status code is part of the HTTP/1.1 standard (RFC 7231).[1] The Internet Assigned http status codes cheat sheet Numbers Authority (IANA) maintains the official registry of HTTP status codes.[2] Microsoft IIS sometimes uses additional decimal sub-codes to provide more specific information,[3] 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).

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. 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.[4] 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). 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. The response 417 Expectation Failed indicates the request should not be continued.[2] 101 Switching Protocols The requester has asked the server to switch protocols and the server has agreed to do so.[5] 102 Processing (WebDAV; RFC 2518) A WebDAV request may contain many sub-requests involving file operations, requiring a long time to comple

code. Since HTTP/1.0 did not define any 1xx status codes, servers MUST NOT send a http 502 1xx response to an HTTP/1.0 client except under experimental conditions. A client MUST be prepared to accept one or more 1xx status

responses prior to a regular response, even if the client does not expect a 100 (Continue) status message. Unexpected 1xx status responses MAY be ignored by a user agent. Proxies MUST forward 1xx responses, unless the connection https://en.wikipedia.org/wiki/List_of_HTTP_status_codes between the proxy and its client has been closed, or unless the proxy itself requested the generation of the 1xx response. (For example, if a proxy adds a "Expect: 100-continue" field when it forwards a request, then it need not forward the corresponding 100 (Continue) response(s).) 10.1.1 100 Continue The client SHOULD continue with its request. This interim response is used to inform the client that the initial part of the request has https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html been received and has not yet been rejected by the server. The client SHOULD continue by sending the remainder of the request or, if the request has already been completed, ignore this response. The server MUST send a final response after the request has been completed. 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. The server will switch protocols to those defined by the response's Upgrade header field immediately after the empty line which terminates the 101 response. The protocol SHOULD be switched only when it is advantageous to do so. For example, switching to a newer version of HTTP is advantageous over older versions, and switching to a real-time, synchronous protocol might be advantageous when delivering resources that use such features. 10.2 Successful 2xx This class of status code indicates that the client's request was successfully received, understood, and accepted. 10.2.1 200 OK The request has succeeded. The information returned with the response is dependent on the method used in the request, for example: GET an entity corresponding to the requested resource is sent in

Owner TooTallNate commented Mar 24, 2014 Repro code? Nothing has changed as of recently AFAIK jonathanong commented Mar 24, 2014 don't have repo code. just a test in cojs/cogent: cojs/cogent@ec707e2 not sure what's going on. works in 0.11.11 but fails in 0.11.12. getting: Error: Protocol:https: not supported. at new ClientRequest (_http_client.js:70:11) at Object.exports.request (http.js:52:10) at Object.exports.request (https.js:136:15) at Context.request (/Users/jong/Workspace/cogent/lib/index.js:167:39) at next (/Users/jong/Workspace/cogent/node_modules/co/index.js:93:21) at Context.
our CheckUpDown robot). The methods defined by the HTTP protocol are as follows: OPTIONS: Find out the communication options available for a particular URL resource. Allows the client to determine the options and/or requirements associated with a resource, or the capabilities of a server, without a specific action involving transfer of data. GET: Retrieve the information identified by the URL resource e.g. GET a particular Web page or image. The most common method by far. HEAD: Identical to GET except that the server returns header information only, not the actual information identified by the URL resource. Useful to obtain metainformation about the entity implied by the request without transferring the entity-body itself. Often used to test hypertext links for validity, accessibility, and recent modification. POST: Submit data to the Web server such as 1) post a message to a bulletin board, newsgroup or mailing list, 2) provide input data - typically from a CGI form - to a data-handling process, 3) add a record directly to a database. PUT: Set (place/replace) the data for a particular URL to the new data submitted by the client. For example, upload a new Web page to a server. DELETE: Remove the data associated with the URL resource. For example, delete a Web page. TRACE: Run a remote, application-layer loop-back of the request message. Effectively a 'ping' which tests what data the Web server is receiving from the client. CONNECT: Reserved for use with tunneling (e.g. SSL) via a proxy server. This method is defined only for HTTP version 1.1, not the earlier version 1.0. If the method in the request HTTP data stream is not one of the above, then a 501 error will result. Or the method may be valid but not actually supported by the Web server. This typically only happens for newer methods such as CONNECT when received by older Web servers. (Last updated: March 2012). Fixing 501 errors - general This error should be very rare in any Web browser. It is more likely if the client is not a Web browser - particularly if the Web ser
