## 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 shouldn’t impact your server code.) NOTE: page.setExtraHTTPHeaders does not guarantee the order of headers in the outgoing requests.

<b>Signature:</b>

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

## Parameters

|  Parameter | Type | Description |
|  --- | --- | --- |
|  headers | Record&lt;string, string&gt; | An object containing additional HTTP headers to be sent with every request. All header values must be strings. |

<b>Returns:</b>

Promise&lt;void&gt;
