HTTP Headers Analysis Tool

Understanding HTTP Headers

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.

Common HTTP Headers

Here are some common HTTP headers and their purposes:

  • Content-Type: Indicates the media type of the resource.
  • Cache-Control: Directs caching mechanisms on how to handle the response.
  • Content-Security-Policy: Helps prevent Cross-Site Scripting (XSS) attacks.
  • Strict-Transport-Security: Enforces secure (HTTP over SSL/TLS) connections to the server.
  • X-Content-Type-Options: Prevents browsers from MIME-sniffing a response away from the declared content-type.
  • X-Frame-Options: Indicates whether a browser should be allowed to render a page in a <frame> or <iframe>.
