Status Codes

Status codes are a set of three-digit numbers that are used to communicate the status of a request made to a server. They are an important part of the HTTP (Hypertext Transfer Protocol) protocol, which is used to transfer data on the World Wide Web.

There are several categories of status codes, including 1xx (informational), 2xx (successful), 3xx (redirection), 4xx (client error), and 5xx (server error). Each category has a specific meaning and indicates a different type of response from the server.

For example, a 2xx status code indicates that the request was successful and that the requested action was completed. The most common 2xx status code is 200, which indicates that the request was successful and that the requested content was returned to the client.

A 3xx status code indicates that the client needs to take additional action in order to complete the request. The most common 3xx status code is 301, which indicates that the requested content has been permanently moved to a new location.

A 4xx status code indicates that there was an error with the request made by the client. The most common 4xx status code is 404, which indicates that the requested content could not be found on the server.

A 5xx status code indicates that there was an error on the server while processing the request. The most common 5xx status code is 500, which indicates an internal server error.

Status codes are an important part of the communication between a client and a server and help to ensure that requests are properly processed and responded to.

In conclusion, status codes are a set of three-digit numbers that are used to communicate the status of a request made to a server. They are an important part of the HTTP protocol and are used to indicate the success or failure of a request, as well as the required action to be taken by the client or server.
