As common computer error codes defined by the Hypertext Transfer Protocol (HTTP), an important part of that structure is a status code. common internet error messages Introducing HTTP Status Codes Status codes are three-digit numbers.

These represent informational messages. These are rarely seen. http://royal.pingdom.com/2009/05/06/the-5-most-common-http-errors-according-to-google/ A code of the form 3xx represents a redirection response. Typically, the browser will handle these without user interaction and get the resource from the new location instead. Error codes come in the form of 4xx and 5xx statuses. Error codes at the 400 level mean there was a client-side error — think of something like the user typing the wrong URL in the address bar. Error codes at the 500 level mean there was a server-side error — think of something like the database server going down https://www.globo.tech/learning-center/5-most-common-http-error-codes-explained/ or perhaps running out of disk space. Five of the most popular error codes are 403, 404, 500, 503, and 504. Let’s look at each of these in a little more detail. 404 Not Found The most common error code you run into is a 404 error. The 404 status code means the requested resource is no longer available or, more specifically, just not found. Was it ever available there? You don’t know. You do know it isn’t available there now. What are some of the reasons for a 404 error? Typos are a common reason for getting a 404 error. A missing or extra letter in a typed-in url, or a wrong domain name can often result in a 404 error. Another reason for 404 errors isn’t typos; it is the aging of the web. When someone writes an article or blog, that person might link to a secondary source to provide additional information for the article. Now imagine revisiting said article six months or six years later. If what was linked to is no longer on the web, a 404 error will be generated when you click on the link in the browser. 403 Forbidden Another common client-side response status code is 403. Getting a 403 status code back from an HTTP request means access to the resource is forbidden. This is not an authentication problem; those are 401 (unauthorized) errors. One common reason for 403 errors is the server maintaining a whitelist of machines that can access that system and the user’s machine no

It includes codes from IETF internet standards, other IETF RFCs, other specifications, and some additional commonly used codes. The first digit of the status code specifies one of five classes of response; https://www.maketecheasier.com/common-browser-error-messages/ an HTTP client must recognise these 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 error codes 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 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.
