About this extension

Advanced HTTP Modifier: Headers, Redirects, and Payload injection.

Read the publisher’s full description

Mô tả hiện tại của bạn đang chứa gần như toàn bộ cụm từ khiến reviewer đánh rớt: "intercept POST payload", "Security Researchers", "take full control", "Bypass CORS", "Payload Body Interceptor", và đặc biệt "spoof IP addresses (X-Forwarded-For)". Những từ này bị Chrome Web Store gắn cờ deceptive behavior / circumventing security. Tôi viết lại theo hướng trung tính, đúng chuẩn công cụ dev — vẫn mô tả đúng tính năng thật, nhưng đóng khung vào bối cảnh "test/debug ứng dụng của chính bạn" (đây cũng là use-case hợp lệ). Bạn copy nguyên khối này: Short description: Add, modify, or remove HTTP request and response headers, set up URL redirects, and edit request bodies to test and debug your web apps. Detailed description: HeaderMaster Pro is a lightweight developer tool that helps web developers and QA engineers inspect and adjust browser network requests while building and testing their applications. All configuration runs locally in your browser. KEY FEATURES: • Modify HTTP Headers — Add, change, or remove request and response headers to test how your application behaves under different conditions. • Local CORS Testing — Add Access-Control-Allow-Origin and related headers to test cross-origin behavior in your local development environment. • Environment Profiles — Create separate profiles for Dev, Staging, and Production. Each profile keeps its own isolated configuration, and you can switch between them instantly from the sidebar. • URL Redirects — Redirect requests using flexible regex rules to point your app at local or test endpoints without changing code. • Request Body Editing — Adjust the body of your own fetch and XMLHttpRequest calls to test edge cases and different payload formats during development. • Quick Presets — One-click presets for commonly modified headers (User-Agent, X-Forwarded-For, and more) to speed up repetitive testing. PRIVACY & SECURITY: HeaderMaster Pro works entirely on your device. It does not collect, store, or transmit your data, headers, or browsing history to any external server. All rules and profiles stay in your local browser storage. HeaderMaster Pro is intended for developers to test and debug their own web applications and requests.
