About HTTP Header Checker
What is the HTTP Header Checker Tool?
The HTTP Header Checker tool retrieves all HTTP(S) response headers for a given URL. Use it to inspect server details, security settings, caching policies, and more.
How It Works
- Enter the full URL (including http:// or https://) of the site you want to inspect.
- Click the Check Headers button to send a request and fetch the headers.
- View the headers in a clear, tabular format for easy analysis.
Key Features
- Protocol Support: Works seamlessly with both HTTP and HTTPS endpoints.
- Minimal Overhead: Uses HEAD requests by default to retrieve headers without downloading the full page.
- Shareable Links: Updates the browser query string so you can bookmark or share your header-check results.
- Error Handling: Provides clear alerts if the URL is invalid or the request fails.
