a6-plugin-cors

Overview

The cors plugin manages Cross-Origin Resource Sharing headers on APISIX routes. It automatically handles preflight OPTIONS requests, sets Access-Control-* response headers, and supports wildcard, exact, and regex-based origin matching.

When to Use

• Enable browser-based JavaScript access to your API from different origins
• Configure credentialed cross-origin requests (cookies, auth headers)
• Allow specific subdomains via regex patterns
• Control preflight cache duration for performance
