About HTTP Header Parser
HTTP Header Parser reads one `name: value` header per line, normalizes names to lowercase and summarizes Content-Type, Cache-Control, HSTS, CSP and X-Content-Type-Options presence. Use it to organize a copied response-header sample during debugging. For example, a Cache-Control line is surfaced as the detected cache policy. The parser does not make a network request, preserve repeated header fields, interpret every directive or prove a secure or correct response. Values containing additional colons are retained after the first separator. Processing stays in the browser; redact cookies, authorization data and internal host details.
