HTTP Response Status Codes | CyberNcrypt
HTTP status codes are like short server notes that are tacked onto a web page. They are not part of the site’s content. They are instead messages from the server informing you of how things went when it received the request to view a specific page.
When you click on a link or enter a URL and press Enter, your browser sends a request to the web server for the site you’re attempting to access. The server receives and processes the request before returning the relevant resources and an HTTP header. The HTTP header contains HTTP status codes that are delivered to your browser. While status codes are returned every time your browser requests a web page or resource, you rarely see them.
Understanding HTTP response status codes is critical if you are a website owner or developer. HTTP response status codes, when they appear, are a valuable tool for diagnosing and correcting website configuration errors.
