HTTP (Hypertext Transfer Protocol) is a protocol that allows communication between clients and servers on the web. When a client sends a request to a server, the server responds with an HTTP status code. These codes indicate the status of the requested resource and help in troubleshooting and debugging issues.
In this article, we will discuss the different HTTP status codes, their meaning, and how they can be useful for IT development.
HTTP status codes are three-digit numbers that indicate the status of the requested resource. There are five categories of HTTP status codes:
Let's take a closer look at each category.
The 1xx status codes indicate that the request has been received and the server is continuing to process it. These codes are used for information purposes and do not indicate an error.

The 4xx status codes indicate that the client has made an error in the request. These codes are accompanied by a message that explains the error.

The 5xx status codes indicate that the server has encountered an error while processing the request. These codes are accompanied by a message that explains the error.
Some of the most common 5xx status codes are:
HTTP status codes are an essential part of web development. They help in troubleshooting and debugging issues and can improve the overall user experience. Understanding the different status codes and their meaning can help in debugging and resolving issues quickly.
