This prevents Web clients from interacting directly with Triple services. Proposed Solution Natively support CORS at the Triple Protocol layer, allowing users to handle cross-origin requests by configuring an allowed origin whitelist. ### 📋 Use Cases ```go protocol.WithTriple( triple.WithCORS( triple.CORSAllowOrigins("[https://example.com](https://example.com)", "https://*.sub.example.com";), triple.CORSAllowMethods("POST", "GET", "OPTIONS"), triple.CORSAllowHeaders("Content-Type", "Authorization"), triple.CORSExposeHeaders("X-Custom-Header"), triple.CORSAllowCredentials(true), triple.CORSMaxAge(3600), ), ) ``` ### ⚖️ Complexity & Risks _No response_ ### 🔗 External Dependencies _No response_ ### 📘 Additional Context _No response_ -- This is an automated message from the Apache Git Service.
