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. Common HTTP Status Codes 200 OK The request was successful. This is the standard response for working pages. 301 Moved Permanently Moved Permanently. This content has been moved to a new URL forever. Good for SEO redirects. 302 Found Found (Temporary Redirect). The content is temporarily at a different location. 403 Forbidden Forbidden. The server understands the request but refuses to authorize it. 404 Not Found Not Found. The server cannot find the requested resource. 500 Internal Server Error Internal Server Error. The server encountered an unexpected condition.
