HTTP headers are an essential part of the web. They carry information about the client browser, the requested page, the server, and more. Properly configured headers can improve security, performance, and user experience.
Here are some common HTTP headers and their purposes:
HTTP headers are key-value pairs sent between the client and server with each request and response. They provide essential information about the request or the response, or about the object sent in the message body.
HTTP headers are important because they control how content is transferred and rendered. They can also enhance security by enabling policies like Content Security Policy (CSP) and Strict Transport Security (HSTS).
You can check your website's HTTP headers using online tools like the HTTP Headers Analysis Tool provided on this page. Simply enter your website's URL and start the analysis.
