Understanding the 1xx Informational Status Code

When it comes to HTTP requests, you're likely familiar with the standard response codes like 200 OK or 404 Not Found. However, there are other status codes that might be less well-known, including the 1xx Informational status code. In this article, we'll explore what a 1xx Informational status code means and how it fits into the world of HTTP requests.

What is a 1xx Informational Status Code?

A 1xx Informational status code is a temporary response that indicates the server has received your request and is continuing to process it. It's not a final response, but rather a intermediate message that lets you know the server is still working on your request.

The 1xx Informational status code is intended to be used with other HTTP headers, such as the Link Header. This header allows you to specify additional information about the requested resource, which can be useful in certain situations.

Other 1xx Status Codes

While we're talking about 1xx Informational status codes, it's worth mentioning some of its cousins: 100 Continue, 101 Switching Protocols, 102 Processing, and 103 Early Hints. Each of these status codes serves a specific purpose, such as allowing the client to continue with the request or indicating that the server is switching protocols.

When Do You Encounter 1xx Status Codes?

In most cases, you won't encounter 1xx status codes frequently, as they're usually used in specific situations. For example, if you're making a long-running request and want to keep the client informed of the progress, a 102 Processing status code might be used.

In conclusion, the 1xx Informational status code is a temporary response that indicates the server has received your request and is continuing to process it. While it's not as well-known as other HTTP status codes, understanding what a 1xx Informational status code means can help you better navigate complex HTTP requests and interactions. By knowing how to use these status codes effectively, you can build more robust and responsive web applications that provide a better user experience.
