HTTP response codes are used to indicate success, failure, and other properties about the result of an HTTP request.

Each HTTP response is accompanied by a status code, and they are broken into five categories. Each of the response status codes is used to convey general information about the outcome of the request.

Let's explore some common HTTP Status Codes because who knows you shall need them tomorrow and after that the whole list of all the Codes for reference!

But before that, let's read about a fun fact.

🤓 Fun Fact

Believe it or not, "418 I'm a Teapot" is a legitimate HTTP status code, although it comes with a twist of humour!

It was originally part of an April Fools' joke 🤡 by the Internet Engineering Task Force.

This status code was introduced in the "Hyper Text Coffee Pot Control Protocol" (HTCPCP) in 1998.
