About HTTP Header Analysis
HTTP headers are the core part of HTTP requests and responses, carrying information about the client browser, the requested page, the server, and more.
- Status Codes: Quickly identify if a page is working (200), redirected (301/302), or missing (404).
- Redirect Chains: Trace the path of a URL to see all intermediate hops before the final destination.
- Server Info: See what software the server is running (e.g., Nginx, Apache) and caching policies.
