## Page.setExtraHTTPHeaders() method
The extra HTTP headers will be sent with every request the page initiates. NOTE: All HTTP header names are lowercased. (HTTP headers are case-insensitive, so this shouldnt impact your server code.) NOTE: page.setExtraHTTPHeaders does not guarantee the order of headers in the outgoing requests.

```typescript
setExtraHTTPHeaders(headers: Record<string, string>): Promise<void>;
```
