About the HTTP Header Viewer
Easily inspect the full HTTP response headers from any URL. This tool fetches the headers from a target URL and displays them in a clean, readable table, helping you debug server configurations, caching policies, and more.
HTTP headers contain critical information about a server's response that isn't visible on the web page itself. This tool saves you from using complex command-line utilities like `curl`, providing a quick and clear way to see headers like `Content-Type`, `Cache-Control`, and `Content-Security-Policy`. It's essential for debugging and understanding how a server is configured.
