About HTTP Headers

HTTP headers carry important information between web browsers and servers. This tool helps you analyze:

  • Status Code: HTTP response status (200, 404, 500, etc.)
  • Server Information: Web server software and version
  • Content Type: MIME type of the response content
  • Security Headers: HSTS, CSP, X-Frame-Options, etc.
  • Caching Headers: Cache-Control, ETag, Last-Modified
  • Compression: Content-Encoding (gzip, deflate, br)

Understanding HTTP headers is essential for web development, security analysis, and performance optimization.
