Frequently Asked Questions
HTTP headers are metadata sent between clients and servers during HTTP requests and responses. They contain information about content type, caching, security policies, cookies, and more.
Checking headers helps debug web scraping issues, verify security configurations, analyze caching behavior, understand CORS policies, and diagnose connection problems.
For scraping, pay attention to Set-Cookie (session management), Content-Type (response format), Cache-Control (freshness), and any custom anti-bot headers.
