sidebar_label: Page.setExtraHTTPHeaders

# 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.
**Signature:**
```typescript
class Page {
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. |
**Returns:**
Promise&lt;void&gt;
