转换规则现已在 vercel.json 中可用

You can now define transform rules in vercel.json to modify HTTP request and response headers or query parameters, without changing application code.

Set, append, or delete request headers, response headers, and query parameters
Use conditional logic to apply changes based on request metadata
Match by equality, inequality, prefixes, suffixes, inclusion in string arrays, or numeric comparisons for fine-grained control

This expands the flexibility of Vercel's CDN, which already supports routing behavior like redirects and rewrites to external origins.

For example:
