## 7. Headers API
Transport constructors and `RequestInfo.headers` now use the Web Standard `Headers` object instead of plain objects.
Transport constructors now use the Web Standard `Headers` object instead of plain objects. The custom `RequestInfo` type has been replaced with the standard Web `Request` object, giving access to headers, URL, query parameters, and method.
```typescript
// v1: plain object, bracket access
// v1: plain object, bracket access, custom RequestInfo
headers: { 'Authorization': 'Bearer token' }
extra.requestInfo?.headers['mcp-session-id']
// v2: Headers object, .get() access
// v2: Headers object, .get() access, standard Web Request
headers: new Headers({ 'Authorization': 'Bearer token' })
ctx.http?.req?.headers.get('mcp-session-id')
new URL(ctx.http?.req?.url).searchParams.get('debug')
```
