About the HTTP Header Parser
The HTTP Header Parser allows you to inspect request and response headers from any URL. Headers contain critical information about content type, caching, cookies, redirects, and security policies.
Why use an HTTP Header Parser?
- Debug server responses and identify issues
- Check security headers like HSTS, CSP, and CORS
- Monitor redirects and caching behavior
- Useful for SEO audits and performance optimization
How to use the tool
- Enter the URL of the webpage you want to analyze.
- Click Parse to fetch and display HTTP headers.
- Review the header information for debugging or optimization.
Example
Sample response headers:
HTTP/1.1 200 OK
Content-Type: text/html; charset=UTF-8
Cache-Control: no-cache
Strict-Transport-Security: max-age=31536000; includeSubDomains
Tips
- Always check for missing security headers (CSP, X-Frame-Options, etc.).
- Use headers to understand caching and improve load times.
- Verify redirect chains to avoid SEO and performance issues.
