the most common acronyms that you will encounter is HTTP, which stands for Hypertext Transfer Protocol. This is considered the center of data and information exchange on the web.
Http Error Code
HTTP is an application protocol that acts as a request-reply system that involves a http code 403 client and a server. Request-reply or request-response is one of the simplest ways used by computers to communicate with each http code 302 other. The original version of HTTP, officially called the HTTP/1.0 was revised into HTTP/1.1. However, since the inception of the first version, status codes have already been present. One of the most prominent status codes
Http Response Example
is the 1xx, but before you get to know about what exactly 1xx is, it is important that you understand first what status codes are. In HTTP/1.0 and the subsequent versions of the protocol, whenever a request is performed, a response is triggered. The request methods include GET, HEAD, and POST. When the HTTP/1.1 came out, five new methods were introduced. These are OPTIONS, DELETE, TRACE, CONNECT, and PUT.
Http Status Codes Cheat Sheet
Methods namely HEAD, GET, TRACE, and OPTIONS pose no harm to the server and thus, they are considered “safe methods.” On the other hand, POST, DELETE, and PUT may give adverse effects on the server and sometimes on transactions and other transmissions. More about Status Codes The HTTP response consists of the status line, which is the very first line of the protocol’s response to the request. This also contains a number along with a human readable phrase called the “reason phrase.” The user agent or the software agent will handle the response depending mainly on the code. The response headers are also considered to determine how the user agent reacts. There are custom status codes that can also be used, particularly if the software agent does not recognize the code. Status codes can only be read by machines, which is why reason phrases were created. In reality, the reason phrases are simply recommendations, so the user or the human reading the message can obtain further information especially about the nature of the issue. A web developer can replace the reason phrases with his own version or any “local equivalent” of the code. The 1xx HTTP Status Code 1xx stands for 100 up to

Protocol (HTTP) response status codes. It includes codes from IETF internet standards, other IETF RFCs, other specifications, http 502 and some additional commonly used codes. The first digit of the status code specifies one of five classes of response; an HTTP client must recognise these five classes http://www.websitepulse.com/blog/what-is-1xx-http-status-code 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 Numbers Authority (IANA) maintains the official registry of HTTP status codes.[2] Microsoft IIS sometimes uses additional decimal sub-codes to provide more specific https://en.wikipedia.org/wiki/List_of_HTTP_status_codes 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).

codes HTTP status codes Below is a list of response codes for HTTP returned by servers on the Internet. Most of http://www.ascii-code.com/http-status-codes.php these status codes are specified by RFC 2616, while some are unstandardized http://www.restapitutorial.com/httpstatuscodes.html status codes which are also used on the web. The codes help identify the cause of the problem when a web page or other resource does not load properly. The response code ranging from 1XX to 5XX. 1xx Informational Responses HTTP status codes in the 1xx are http error typically informational. 100 Continue 101 Switching Protocols 102 Processing 103 Checkpoint 122 Request-URI too long 2xx Successful Responses Status codes in the 2xx range indicate that the transaction was received, understood, accepted and processed successfully. 200 OK 201 Created 202 Accepted 203 Non-Authoritative Information (since HTTP/1.1) 204 No Content 205 Reset Content 206 Partial Content 207 Multi-Status (WebDAV) (RFC http error 1xx 4918) 226 IM Used (RFC 3229) 3xx Redirection Responses HTTP status codes in the 3xx range pertain to redirection. The client must take additional action to complete the request. 300 Multiple Choices 301 Moved Permanently 302 Found 303 See Other (since HTTP/1.1) 304 Not Modified 305 Use Proxy (since HTTP/1.1) 306 Switch Proxy 307 Temporary Redirect (since HTTP/1.1) 308 Resume Incomplete 4xx Client Error HTTP status codes in the 4xx range indicate that a problem occurred with the request. 400 Bad Request 401 Unauthorized 402 Payment Required 403 Forbidden 404 Not Found 405 Method Not Allowed 406 Not Acceptable 407 Proxy Authentication Required 408 Request Timeout 409 Conflict 410 Gone 411 Length Required 412 Precondition Failed 413 Request Entity Too Large 414 Request-URI Too Long 415 Unsupported Media Type 416 Requested Range Not Satisfiable 417 Expectation Failed 418 I'm a teapot (RFC 2324) 422 Unprocessable Entity (WebDAV) (RFC 4918) 423 Locked (WebDAV) (RFC 4918) 424 Failed Dependency (WebDAV) (RFC 4918) 425 Unordered Collection (RFC 3648) 426 Upgrade Required (RFC 2817) 428 Precondition Required 429 To
consisting only of the Status-Line and optional headers, and is terminated by an empty line. There are no required headers for this class of status code. Since HTTP/1.0 did not define any 1xx status codes, servers MUST NOT send a 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 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).) Wikipedia Request received, continuing process. 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 send a 1xx response to an HTTP/1.0 client except under experimental conditions. 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 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. Wikipedia This means that the server has received the request headers, and that 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). If the request body is large, sending it to a server w
