HTTP is the protocol used by the entire internet to interact seamlessly. When you type something in your browser, the browser sends your request to the destination servers in keeping with the HTTP protocol. When the servers respond to the request, they do it by following the HTTP protocol. HTTP Server Headers provide useful information about the web server, where a particular website is hosted. This information includes the URL of the page that is stored on the server, content type, SSL verification status, and a lot more. HTTP Server Headers offer a good insight into the performance of your web server from your user’s point of view.
